Wife is having an emotional affair

[Alan A.]

last night was the first time that I slept alone since before my wedding, It was a little rough. W came home today for a couple hours and got something to eat then watched some TV. Then she asked if it was ok for her to go to a friends (a little weird because she never asks me if I care what she does anymore) I told her that she could go if she wanted and that I couldn't control her. She said that she was going to one of her gf's house but just observing her behavior and the way she was talking made it seem like she was hiding something. She's probably with OM. I've been trying to decide what to do, do you think I should definitely move out or should I wait for her to make a move? I've talked to her about it a little, our lease is up in may and asked her if we should find other places to live. She said that she would want to stay here even if I leave. I don't know if she would move out if I stayed. What do you think?
