Another concern of mine that I can't wrap my mind around is that we are only married 2 years, no kids. So opting out seems easier than for some other ppl married 10+ years and children..or am I wrong?
OH, I think it's infinitely easier (or at least simpler?); most of us, if we hadn't had kids, would have probably done things anywhere from a little bit differently to WAY differently. I know I would have.
If I were in your shoes, I'd simply move on, learn to improve my own life, and hope to reconnect with my wife someday IF she "did the work" (went thru the necessary introspection to figure out why she would respond to marital challenges with the destructive and selfish decision to have an affair, and then lie about it). But that's just me.
