Marriage like life is a game. If you try to play fair you generally lose. It is sad but that is real world stuff. My suggestion... lawyer up and call it a day. You have no kids to worry about, which allays a huge part of the issue of getting divorce. You said she has a job, so alimony should be limited to none. You caught her on the phone saying this stuff, very likely she's already had sex. Now, you cheated as well, so you are not necessarily better but she doesn't know so you should NEVER admit that, keep the leg up in case you need it (when she tries to demand too much in the split). But get out now, this is not going to get better. Weight loss surgery is like a new set of tits. Now she thinks she is god's gift because a few guys give her attention (sad reality many women refuse to realize, guys will hit on anything that is remotely fuckable) and she is gonna get hers. Obviously as someone with anxiety/depression this is not going to go well for you to discover the truth - which likely will be dick pics, and graphic descriptions of her escapades. In the long run you are going to be better off and far more happy. I am positive of that. Good luck sir!!
