Oh, GH. First of all, don't make any decisions just yet. She shouldn't either, but we know no one can control her. She is mentally unstable. There I've said it. I have typed it and erased it many times, but this time I'm printing it. Your wife needs profession mental help. This is so beyond a question of do I love this man or that man. This is a matter of which psychologist can help her and how long the treatment will take.
I think OM figured this out already and he is really done with her. So she will be on a flight back to you soon. She has destroyed everything good in her life. Please get her help first before you focus on what she is doing to you.
