Okay, to make it short:

Met a Girl in my class -> were friends for about 6 months -> then had 3 great dates where she came over and stayed the night.

The semester then started and she told me she wouldnt have time during the first two weeks. (Yet I kept asking her if we could meet up)

I started to get clingy but at the same time I tried to show her that I have better things to do. I got on her nerves big time but she didnt tell me and just ignored me. We then had a lot of fights (all online) and she wouldnt have any time for me at all. But I didnt want to look too sad so I just confronted her with everything weekly until she finally went invisible. Have seen her twice at parties where she wouldnt talk to me - didnt show her that i cared too much. She still hasnt admited anything (not even being invisible to me) and its been three months now.

I did pretty much everything wrong that I could have. But she still talks to me, but I have to initiate the chat and she isnt really to talkactive. (I only message her like once a week right now)

She is a really shy and complex person (studies physics haha), knows what she wants, barely shows feelings or emotions and is stuck up. She never admits something, even when proofen.

I could easily move on and did have a few dates during that time. But since its not too much effort to just talk to her online I figured I can give it a try to "game" her a little. I know she likes me and finds me attractive, but she is mad and told me if i`d change there might another chance. An almost impossible situation to get out of and just i know that i should read between her lines. But Im sure, if I give it a little time I can make it happen. haha

So, I guess I need some advice on how to figure out if she
- "thinks Im stalking her and is scared"
- "is really mad at me"
- "doesnt give a damn anymore and just talks to me when she`s way to bored"

Knowing that, can determine my next steps... not contacting here for a few months or showing her that i do care about here. (she once asked me about the last time i said something nice)

I read something on this board which might work for me. I could initiate a conversation and ask her for some advice: "Hey, there`s this really cute girl I met but I think she`s really mad and its really difficult to talk to... what should I do?" Could this work to open her up a little bit? I already appologized to her about two weeks ago and she said "thanks" ... but nothing changed except for the fact that she still doesnt want to see me right now

I could give you guys a lot more details but i dont really want to bother anyone with this "dude move on crap" and i think this sums it up.

maybe this will make it more clear: is it even possible to "game a make up" ?
