feel like such a shitty girlfriend.

My boyfriend HATES when I cry. It doesn't matter what it's about it puts him in a blind rage. In those moments I just need someone to comfort me but instead he heightens it by yelling and getting frustrated. Outside of the situation I'm able to talk to him about it and he understands but in the situations it just pisses him off. I beg him to hold me and just BE NICE but it's like he's incapable in that moment. I just don't know what to do anymore.....
