I meant to post the other day and got involved with kids things.
I agree with Snodderly....You have jumped from one man to another, yet have not stood on your own. If you return to the rental house, I just fear that you will return to unaddressed issues....and then run again.
Maybe a short term rental (3-6 months maybe) and a clear list to your husband.
1-I want to come home 2-To do that we need to address our prior marital issues including the OM 3-Revisit MC 4-Start "dating" again 5-Then move back in
You are in a good place...Hopefully we can assist you in getting farther.
