When I first read this, I thought the same thing Trippin2.0's wrote, but then I didn't see her as a "bad" person (abusive, manipulative...). I think she's trying to put things in order in her life and run from what went wrong, but that's a shhtty way to do it. You can't run away from your past, that's childish of her.

She was/is being a real coward and maybe hasn't realized this is rebounding in her relationship. She made a fool out of you, even if she didn't mean to. This is a great anxiety-breeding circle. I'd put her up on the wall and ask her if she's going to grow a pair or what.

Idk, this sounds like something that would happen in the first 6 months of a relationship starting from 0, not between a married couple.
