I started talking to my ex in January and we started officially going together in February. Everything was going fine and stuff for the first couple of months, but after I had a few AFC moment things started to go down the drain. The last time me and my ex had sex was early last month and the last time we saw each other was a week after having sex at school during exam weeks.

My ex was going through a lot of things during the last couple months of our relationship (her grandma died and left her an inheritance, and her family was not happy they didnt get any of the inheritance money so they were acting funny with her) so I understand her mind hasn't been in the right mind state in a while. The thing that grinds my gears though is the actions of hers just recently. The Sunday before Memorial day I went to the city (Chicago, I stay out in the burbs) to hangout with my family, and while I was out there I got a text from her asking what I was doing. I told her I was at my aunts house and she got somewhat upset because I didnt tell her I was going to be out there.

I played it off and went about my business. The next day I texted her early in the morning to let her know I might be in the city today, she took forever to respond and was being very short with her text so I said fuck it. The next day I didn't text her at all, but I did eventually call her late at night. We both talked and she was being pretty responsive etc., but out of no where she started being cocky on the phone. She told me she was going to be out my way at 1 so I made a comment about I was going to be out there around the same time. She in turn says" what do you have to do out there, you don't have anything to do out there, you just want to see me". I responded back with a smart ass comment and kept it moving.

The next day I text her at 3 something because I know she usually is running late and she text me back telling me she had already came out my way to go to the school at 8 am and left. This was blatant disrespect to me (I mean if she really respected me she would of hit me up letting me know she was going to change her plans etc.) so I said fuck it and stopped talking to her that day. The next day she text me at night (10 something) asking me what was I doing and I didn't respond until like 130am and I told her I had just got home and asked her what she was doing. In the process of waiting for her to text me back I passed out (I had been drinking that night),she texted me back rather quickly saying "Out" (I didn't see this until the next morning though). By the time I saw that text I was fed up and I decided to soft next her. I didn't speak to her for the next two days. I messed up though and called her early in the morning on the 3rd day and her phone rang twice and went to voice mail then an hour later she called me back but my phone only vibrated once, so I called her back and she didn't pick up.

At this point I said fuck her and decided that I wasn't going to text or call her until she text or call me first. This was back on the 4th, she hasn't texted me or called me since the 2nd, but she did leave a message on my SPAM back on the 13th saying -_-. Which confused the hell out of me. Idk what I should do right now, I mean I have already started the move on process but my mind still needs to have some closure. Can any of yall give me some insight please.

Details I forgot to mention:
-She claims to be straight but she has messed with more girls than guys. (Im only the second guy she said she has had sex with.)
- On her twitter she was flirting with studs and bi chicks. She unfollowed me off her twitter for replying to her reply of one of my original tweets. Which was odd to me and quite sketchy.
-I think she believes I have been subliminally talking shit about her on my Facebook statuses, but I really havent been my recent statuses were talking about someone else.
-Her Facebook said she was interested in women a few days ago but she changed it recently to interested in nothing.
-On her twitter I caught a tweet of hers saying some shit about I just tried to break up with my gf and she called me back like nothing happened. Which leads me to believe she might of had a gf this whole time and was just using me for dick smh.
I've been no contact with her since the 4th and I havent been on her Facebook or Twitter since that time either. Do you think she is trying to shit test me by messaging me -_- on my SPAM the other day?
Should I respond back or stay no contact? I kinda want to keep her around as a fwb. If I dont talk to her for the rest of the summer though, I know I will see her this fall at school (we go to the same college) and I dont want it to be awkward or anything. I feel like assumptions and miscommunication ruined us.

Obviously it's over. Man up and initiate the conversation to make it official and you can move on.
