Need to vent - "I feel so betrayed..."

I feel so betrayed. I feel like if you want to step out and be with someone else, then be a man and tell me that.

But he wants to have his cake & eat it too. If it weren't for me, he'd have nothing. He wants to act like he has so much to other women but really he's got nothing.

I've been there for him for 12 years - through things I never would've even gone through in my life.

But he's calling another woman his wife and telling her he loves her. How wrong is that? I'm so hurt.
