Cannot stop crying please help!!!

My heart is so broken right now I cannot stop crying. So my husband and I have been having sex problems for awhile now. he is 28 he says he needs his dick sucked to get hard which I usually suck his dick almost everytime we have sex and a lot of the time just because I want to and I usually get nothing in return. Well I told him last time we had this conversation that I don't need to do it every time or at all it's because I want to. Tonight I decided not to suck his dick and he said fine we aren't having sex. I said we already had this conversation just because I don't want to suck your dick doesn't mean I don't want to have sex. I don't ever ask for him to eat me out if he does its all on his own I made this point to him plus a lot of other points. He then proceeded to say that his dick can't get hard because my vagina is not tight like it used to be since I've had 3 kids. I was so hurt by this comment I told him I don't want to have sex anymore because what you said hurt me that deep I just won't be able to do it because I'll always remember his comment. he feels as if I'm overreacting and he doesn't care that it hurt my feelings he said I deserve for him to say that. We also wanted a big family which I definitely won't be having anymore because of this I'm just so hurt was I wrong what should I do?
