I don't think people are done with you, keep posting. However, you can expect some level of frustration when you are given excellent advice by people who are in a position to, and then you ignore it. Try asking directions from a person a few times and keep turning left instead of right. Bet they get a little pissy too.
Now, I will say I have not dealt with a cheating wife before, but you need to remember you are dealing with a breach of trust and not just a relationship problem. I am going to be blunt here. She screwed your friend and lied to your face about it. Why would her character suddenly change? A complete severing of ties comes with VERIFIABLE by you no contact. Remember, trust is earned, not given.
If you move back in and take the load off, you have again proven yourself weak and manipulable as well as removing incentive for her to make real changes. Again, why would you even want to be friends with somebody who cheated on you? Marriage overides a lot, but she has to EARN the relationship back!
