I recently broke up with my ex whom I dated for a year and a month, through the relationship, trust issues were an underlying problem, always doubting me and always picking fights whenever I talk to another girl. So this went a good two months and it died down eventually. But we decided to break it off about a month ago, went NC for two weeks then went to a concert with her that we planned a while ago. Everything went smooth for four days then all of a sudden she starts getting ticked off and shows no respect. She hung up on me for about 15 times, blocked me on facebook 6 times cause she thinks I was still lying to her about stuff when I changed for the better for her. I just thought it was childish for her to go to the extreme of blocking me, out of nowhere too, but yeah about two weeks ago I called her and told her that I accept the breakup and we should see other people and get some space right? she agreed and I said bye to her. On saturday her cousin posted a status that I disagreed on so I messaged her and gave her some advice, then followed up on her yesterday on her situation, THEN ALL OF A SUDDEN. My ex texts me and says "you're messaging my cousin now? you're such a fucking creep." "I can't believe you're talking to younger girls and trying to help them with their problems." then I said "I gave her a piece of my mind, told her its up to her what she wants to do. she then responded with "you disgust me, I don't even wanna think about you, stay away from me and my family. I'm blocking your number now." then I said " BYE "
I love her so much but this is the part of her that I hate the most, it's mainly kiddy shit, she doesn't seem to be getting any mature than her age, she's 20, I'm 23. I need help on how to handle the current situation, NC and get back with her or move on?
