Is it normal my anxiety scared my boyfriend away?

Judging by the reactions I've been getting out of other people... one of my friends is now saying she wants to kick his ass. :x I mean, I'll put up with a lot if I'm really committed to something. But how can he insult me, throw me, scream in my face and tell me he wants me to be scared and then turn around 2 days later and claim he did nothing wrong.

:/ I do hope he can work on his temper, apparently he's lining up another girl already. One with 2 kids. Who knows, maybe I was enough of the problem that he won't snap on her, but the thought of that happening does scare me... though it's so hard to really feel convinced, plenty of people still seem to think I'm just being weak and oversensitive. Maybe I am.

I don't even know if a professional would give me an accurate judgement because I feel like they might try to be too nice to me, since it is their job to help me. If I need to hear the hard truth I wanna hear it. :x
