Emotional After Sex?! PG-13

So when my husband & I have sex, I love when he cums in me. I get emotionally destroyed (For some weird reason) when he pulls out. Like I actually have to stop myself from tears. It shouldn't be a big deal because we've always pulled out. But now that we've gotten used to him just cuming inside of me, when he doesn't I get upset. Does anyone else ever get this feeling & why?
