Girlfriend wants a break but says she doesn't know why
(for starters I apologise for the large description but I feel I could get more help with a little background information - thanks to anyone who's helpful enough to read it)
Hi, I'm 22 and my girlfriend is 19.. We started going out before uni and we're relatively close to each other (distance wise)now that we're in uni so we see each other almost every weekend.. We've nearly always been fighting in our 8 month long relationship over really unimportant stupid matters. Our fighting "scenario" consists of me usually proving her wrong and her then telling me she feels I always reduce her and make her feel stupid at the end of our fights, but all I do is prove her arguments wrong. Anyway my previous girlfriend really messed me up and it took me 2 years to find my fight relationshipwise, I was following the "manwhore" lifestyle even though I hated it.
Anyway I really care about my current girlfriend and about 2 weeks ago we were literally all over each other, very "lovey dovey".. Then we had a silly argument again and I reacted very stupidly to it as I removed her from my relationship status in faceb**k, I then put my pride up and we didn't talk for two days until I called her and she was quite cold with me but I apologised and we supposedly worked things out but it really hurt her she said.
She then came to visit and we had a good few days but she left early cause she had plans with her friends. This didn't bother me but it did when the next week (which is last weekend in real time) she said she had plans with her friends again and it really bothered me because I was leaving this weekend and it meant we couldn't meet up for a month.
I was very bitter about her putting her friends first and it kept coming up in our conversations and we kept arguing about it.. all she had to do was put me first for one weekend and we wouldve been fine but she didn't and we continued fighting throughout the week. She eventually came on Sunday and we spent the night together and we were fine but I noticed she was different.. and then out of nowhere she wanted a break.
She said "I dont know why I dont know why im not sur eabout us anymore".. this is the type of girl that when she's emotionally overwhelmed her mind kind of blocks up and she just can't respond.. like I honestly feel if we break up she won't come to grips with the reality of that for at least two weeks. Anyway at first I was supportive of it and we cried together for a few hours before she said she's leaving, I told her you can't help how you feel but ill wait for you until you know you're sure about me.. but when she left I called her back to come and she made it difficult at first but eventually she did but she wouldn't change her mind..
After we talked about it she apparently wanted a break but she didn't want to lose me and hence she wanted to talk.. I was all right with that for a few days but then I felt really betrayed and hurt by this and I rejected all of what she said and told her how irrational she was being and how two weeks ago she was a different person but now she doesn't even know if she wants to be with me? And I gave her an ultimatum and told her to decide on me or I was out.. she said she couldn't decide so I told her I would leave her.. after talking to friends though they told me to agree on the break but tell her not to talk and to play it cool.. but the whole idea of a break confused me altogether initially because I was leaving for a month and we weren't going to see each other for a month so it wouldve been a break anyway why on earth would she call it a break? I got paranoid about her maybe preparing to dump me I don't understand...
Anyway today I called her and apologized for being irrational and wanting to dump her and I told her to actually take a break for a while and see if we end up missing each other and after we clear our heads to actually see if its all worth it.. (I HATE PLAYING THESE GAMES IT DRIVES ME CRAZY).. She's always out with her friends like 24/7 they even sleep in the same house sometimes so I'm really worried she won't have time to think about me..
When I told her I agreed with her idea of a break with the condition of us not talking she was a bit surprised and then she had the suggestion of it being open as in being allowed to fool around.. which was a bit shocking but I played it cool and agree'd to it and told her if you feel you're ready to do so then sure..
I know I'm definitely not going to call her for the next week or so and see if she comes back but I'm thinking even if she does I can't talk about our relationship.. do I wait for her to tell me she misses me or something?
What am I supposed to do?
What if she doesn't call me?
A sidenote to all this is that she dyed her hair a completely different colour... paranoid psychologists would say this is a sign that she's turning over a new leaf and she wants something new in her life.. but I dno I don't understand.. why would she want a break but want to talk to me.. she also initially said that she's afraid she's going to regret it.. and she knows she might be making a mistake..
I don't understand what to do..
