<human>: I'll keep this short because Lord knows I could write a book about our relationship. Basically when my boyfriend and I get into fights, he says some really hurtful things that I can't get over. He says that I say hurtful things too but I really don't go as far as he does. 

For example, during one argument he said, "There's nothing left. I have no feelings left for you." And I started crying right away because it was such a reality check and what he said had been confirmed by his recent behavior but he apologized and from then on began acting different. So I felt, of course there are feelings left look how much he loves me. But I just can't get over things like that. I would never say something like that unless it were true. 
   

He says he only says those things when he's angry but is it him getting out what he really feels deep down?

Could you distill the essence of the text into 1-3 sentences?
<bot>: when my boyfriend and I argue, he says really hurtful things. I can't tell if he means them or if they are spur of the moment statements.
