I’m sorry you are going through this right now.

I think I’m a little bit more open in this area then most here so I’ll tell you what I would do. Talk to her and tell her how you feel about it. If her being with a woman is a deal breaker for you then break up with her. If not then tell her your expectations moving forward.

I’m a betting man and I would wager that this isn’t her first rodeo and she likes her some lady parts.

You have some thinking to do.
