She asked if he's gay and messed things up. What would you do?

I recently read a post about a woman who didn't handle her guy's initial effort to tell her that he's into pegging. She asked him if he was gay. Oops. Okay, maybe she's completely new to the idea but still, not a smart move. Now she regrets her reaction and is trying to bring him back around to let her try.

But he's clammed up, won't talk about it, told her it's okay, no need bla bla and maybe they need a break from sex.
But... they've been going out for less than 6 months.

In a relationship that new, saying maybe a break from sex would be a good idea, well... let's face it, that's not good. In fact, it's most likely a way of saying "it's over."

The woman who wrote the post is full of grief now, begging for answers, how to deal with this, how to save the relationship. It's a tough one. Maybe the guy is gay. Maybe not. Maybe he's just not into revealing that part of himself to her. It seems trust was broken when she mishandled things at the beginning.

What would you do if you were her? Would you accept what seems to be the inevitable? Would you keep trying? Should the guy give her another chance?
