Can we let humans be human and have human emotions?? She sounds in denial, which makes me think this is ver go to attitude when conflict arises. For someone to get to the point of saying what he said it's gotta take enduring a lot. It's a normal response if her attitude is anything to go by.

It's not a horrible thing, it's an honest thing. Had he insulted her that would've been something else, but if your partner says that, and you don't dig deeper to find out what's going on, then you really ARE horrible to come to.
Op sounds clingy, like unhealthily clingy.

I agree 100%, sometimes you just need to go into a bedroom and lock yourself up, or go into the living room and have some time to yourself. That doesn't mean you love the person any less, but humans need and deserve time alone, too.

I'm gonna be extra frank here:

1. it sounds like space was needed and you didn't take that seriously
2. you sound kinda clingy.
3. it sounds like you were dumped but you haven't really accepted it yet... which makes me circle back to 2): you sound kinda clingy.
