My XW moved out 3 weeks after BD and I helped her financially. It was worth every penny to not live under the same roof with someone that didn't want to be with me. I was not going to do in house separation for 3 months while she got her ducks in a row. I have no regrets and it had no bearing on whether or not she returned to the marriage.
YOU have to do what is best for YOU!
If you moved out of your house tomorrow would you be able to emotionally handle her bringing men into your home?
