You made only a few posts when you came here years ago, which makes me suspect that one of two things happened:
1. You didn't like what you were told and decided the advice the site offered wasn't applicable to you.
2. You believed the advice could be applied as a quick fix rather than through long term hard work.
I lean a bit towards option 2, based on this quote:
We got back together and for the past few months I thought we were good. It turns out that I was wrong I changed and did what she wanted me to and changed my ways and approaches with her kids on discipline. I quit yelling and started to talk only took fun when it was needed from the kids.
The changes that need to happen aren't just outward actions. They're changes in the ways that you self-reflect, analyze, and communicate. If you had absorbed anything you read here before, you would have understood that you can't walk back into a dumpster fire like you just described and put it out by not yelling anymore. You'd know that after betrayal and sex with other people and the chaos you both inflicted on your children, your marriage couldn't have "been good" for the last few months. That's truly extraordinary rugsweeping.
I'm sorry to hear that you were betrayed. No one deserves that, not even a WS, and even if your marriage was problematic, that didn't give her a license to step out. Unfortunately, we have no advice to give that doesn't require years to implement. Is that really of any interest to you?
