I dont think she is in any type of a, but i do think that she is being coached!
F,
Look, man I know everyone starts out believing that their spouse would never have an A. I am 99% sure your W is in at minimum an ea, probably with the divorced dude she works with. That's why she enjoys talking about work so much.
You are definitely not working on the marriage if she is not inviting you to the wedding and won't have a beer with you.
Her not inviting you to the wedding IMO is a way to start introducing to your family that you guys are having issues and she doesn't know if you can work it out.
You eventually D and then a few months later shockingly she is dating divorced guy.
