Ugh help

So my boyfriend and I have been fighting for a couple days now he’s just really been making me feel bad about myself or about the thoughts I’m having. We finally haven’t been fighting for a little bit well we start to do the dirty he keeps saying he’s about to cum but he doesn’t. So I’m almost 39 weeks pregnant due in 9 days and he can’t even finish after an HOUR!! Which is painful for me! Is there something wrong with me?
