he makes me feel like shit.

I have been dating my boyfriend for a few months now, i love him so much. we have been through a lot together. well my past relationship was very abusive ( both mentally and physically ) and he knows this, i have explained it all to him and have told him why i am the way i am, and by that i mean, why i get so upset when we fight, why i get so upset when he calls me names, why i flinch when he puts his hand towards my face and etc. he understood all of it. well now a few months in and ALL we are doing is arguing, constantly. we just went through a miscarriage about 2 weeks ago and all he has done is make me feel like complete shit, about everything. i cannot handle it anymore. anytime i try to talk to him about it, he goes off and makes me feel even more shitty! I dont even know what to do anymore.
