I'm experiencing something similar, and I have managed to stay no contact for about 7 weeks, but I won't lie: it's been very rough. At first, I was thinking like you, that I should avoid men all together until I feel better, but lately I have been wondering if having a distraction might not be a bad idea, because all I can manage to do is to obsess about this man during all my free time. I think having too much free time makes it harder.
So I guess you can wait until he does something so awful, you can use your anger as a source of strength. I have been reading a lot on this website which I found helpful: http://www.baggagereclaim.co.uk
I have also opted to get some (hopefully short-term) counseling, and started an antidepressant. (Yeah, I'm a wreck! haha)
Relax... I'll need some information first. Just the basic facts - can you show me where it hurts?
