So when you ask your wife to change jobs and/or never see or speak to OM again and she, in return, justifiably requests that you never see or speak to OW as well as your best friend and his wife again what are you going to do?
What a horribly disrespectful thing for your best friend and his wife to do to you and your family. Casually setting you up on a pseudo-date and then leaving you alone with her. Your first mistake wasn't kissing her...it was putting yourself in temptations way. If anything good can come of this (which it probably won't) is that you'll now understand that cheating isn't all that hard to do. Share some laughs, some conversation and a few drinks and, just a few hours later, you FEEEEEEEL like you deserve it.
Feelings LIE.
Just like they did for your wife who imagined herself as all that as Dr. McDreamy picked her out of the crowd of other female minions to give his attention to.
Both of you FINALLY did something for yourself AND IT FEEEELLLLLTTTTTT GOOD.
Sometimes these things have a way of working out and helping recoveries. I hope so for your children's sake but I can't help thinking you'd have been better served just sitting on that couch with your wife friday night and never leaving town.
Are you still communicating with this girl?
If her number is in your phone ERASE IT RIGHT NOW before you lose your mind and start texting and calling this girl like a typical wayward.
Don't go back there until you are divorced.
You do intend to tell your wife about this, right? Your best shot at recovery requires honesty. It'll probably help. Your wife will be hurt and jealous, but now that you are in the same boat she'll see a path of recovery that doesn't involve so much shame and guilt on her part (where she won't feel like you can or will hold it over her head forever). I've seen it go the other way too, where the wayward FEEEEELS they made a mistake and got in to far making their affair an accident whereas your revenge affair is supposedly over the top and intentionally done to hurt them. It's crazy logic but revenge affairs are a double down on crazy. I'm just hoping for the best since I invested so much time and energy helping you.
The internet is 90% complaining and entitlement and I hate it because I deserve better!
