Yes I know all ladies are unique but her traits... I can't find it in any PUA books I've read!. I can easily identify all my previous gfs with cases but certainly not this one

I am 31 now. I have been dating this girl when she was 19 (I was 28) for 1.5 years. Some background information: this girl is a very talented artist (architecture student) and I don't want to over-generalize but she does have this corniness with an artist. She has very high ego yet pretty low self esteem. She isn't close with her family either. We were living together for an year. We both are very jealous type and we fought over the issue many times. We made improvements but apparently we didn't see each other's effort soon enough.

She has some 'bitch friends' who has been encouraging her to use me or dump me but not to treat me too well. (To be fair to them, my ex has this complex of not wanting to show off too much but she'd totally complain about my flaws to them). After I took her to see my overseas families (she loves traveling), I came back with a fever. While I was laying on the coach (day 2 we landed), i asked her to 'distant that bitch like how I distanted my ex'. She already went on Berserk. She literally screamed and dashed out of the house 'wanting to spend the night alone on campus (we live near her college). Her complaint? I ''promised not to mention my ex's names". Since then I moved back to my parents house and let her stay in my apartment. She has been exchanging texts with me telling me to pick up mails, etc. Many of them turned into full-length complaints about me and my parents out of the blue moon. On valentine's day she told me to pick up cookies cuz she baked too much; I refused because I was tired of her cold attitude (although I still loved her). Then I eventually showed up because she started bitching (you get the idea, this repeats). Her birthday is after valentine's and I hand-made her a gift (since she complained I never made nothing while we were together). She seemed impressed when she got it but she still refused to go pick up a burger with me because "sorry I don't feel ready to hang out with you"

Then towards end of February she randomly told me "I'll move out after the semester ends because we'll stay break up forever cuz you cheated". I was like how can I cheat when we already broke up? mat fact I didn't do anything. Turns out I clicked a 'like' on my previous ex's picture with whom I promised to cut all connection.... So I asked her to move out in 3 weeks. After that she started to beg me and complained to my friends how cruel I am, and blah. (I let her stay for free the whole time, including the time we were together). I eventually told her you are free to stay till end of semester but we wont' get back together.

She managed to take a 2-hour train+bus ride to hit me up at my parents' house. Instead of begging for an entry, she was fighting with my parents. (I was unemployed at the time because I was seriously ill). She repeated that two days in a row after that when I was chilling at my friends. Eventually we got back together and we kept it under water since my family is really against her. She promised to move out in May with her only apartment (by herself so I can stay over).

We stayed together again for two months.

I started nagging her to fullfill her promises (like spending more time on us, don't work 18 hours a day and also talked to my mother and apologize for that funny incident she started). I did it on a Saturday, she begged me back saying I am not the only one who wanted to break up but she thought this relationship is really worth working on together. I nagged her again on the following Monday (beginning of May) and she said we are better apart.

3 months has passed. What has she done? Initially she tried to hit up with ex crushes (way far away, not sex is possible; oh FYI I am not her first boyfriend but I am her first sex). Eventually, she went onto focusing on career (she kept changing career plans, too). She told the whole world that she's enjoying her new found freedom.

What she has done behind the scene that I found out? She never liked/commented my friends' and cousins (overseas cousins, too)'s posts. Since we broke, she regularly IM/comments/likes their stuffs. (she sorta did it during first break). However, this time no BS text/email with me. I sent drunk "I miss you I wish things were back to the way it was" SMS. (less than 5 of them total). No response. She initially claimed she wants to avoid me and our mutual friends in the area thinks we are bad combination, too.

Recently she started camping at parties I claimed to be attending (I avoided it because I don't want to cause a huge drama in front of others). SHe tried very hard to get close to my sports group (shes sort of friends with some of them but she doesn't do this sport). Better yet she signed up for a fake account. 3 weeks ago she used it to add my ex, and past weekend, she added me but then immediately removed me after 3 days. I have several theories

1) at my friends' suggestion, I started hanging out with other girls to 1) prove my value 2) so I am less distracted/depressed. I am trying to keep my outlook positive. I know she'd borrow friend's computers to stalk me on FB despiste she blocked me on it

2) I didn't show up at the party the past weekend?

3) I hi'ed that fake account that blocked me now, i told the fake account I have a strong feeling I know her and the profile picture reminds me of 'someone I used to know'. She asked if it is my 'girlfriend' and I played cool and said I have none now and I don't want one for a long while.

2 days after the fake account blocked me. Now here is the funny part, apparently this fake account , a month ago, attempted to add my previous ex, too. And this fake account is full of random friends of my previous ex, plus my overseas cousin's ex bf. (this is also how I am so positive it's her. THe style of writing, and, the fact that there are only 3 people on my fb knows of this ex bf of my overseas cousin because it was pretty underwater relationship: my cousin, myself, and my ex because my ex was visiting Japan with me at that time).

Most people told me it's a bad idea to get back with her but I am willing to work things out with her and encourage to see a professional, say psychologist or something along the line of that. Actually when she begged me back in march, she promised to go only if I accompany her. I had too many interviews across the country at that time so I couldn't make time to do it with her. Now I pretty regret it.

I stalked her youtube favorite list (which is public info). She kept liking either "I miss you" , or "it's not going to work out I am moving on, I enjoy my freedom " songs. I heard girls really like to play with lyrics and I know she's the type who listens to random songs alot when she's depressed for a fact.

She also posted random suggestive comments on her photography blogs. Some ways "I made my bed, I won't return" when she shot a homeless. When she shot houses "I reminisce upon what could have been our wonderful life together". When she shot cyclists, "I rode with you, side by side". And not all her pictures got captions but when she does, its pretty much like that.

so summary: she tries to get close to people around my circle in very passive ways. Some she doesn't even talk to she just 'likes'/comments on their FB and instagram posts. She posts/liked/captioned random messages that seem to suggest messages of two opposite end: "I am done and won't come back", and "I really miss what could have been our love moving forward"

I strongly suggest she has light/mild BPD (bipolar personality disorder). Yes, love is blind, I want her and I am willing to help her.

Thanks!
