I agree, b/c some women keep going back over past mistakes H has made and won't go forward. Once it has been discussed and apologized for....drop it and refuse to go back over it again and if she tries to bring it up....tell her that you won't get off into the past again. If she thinks that is cold hearted, so be it. It is not healthy and sometimes men just have to take a firm stand about that.
I think it is a mistake to apologize for the same thing over & over again. If you apologize 100 times for something you did or didn't do, does that mean you weren't sincere the other 99 times? I don't think men need to apologize until the woman feels better, either, b/c some won't ever feel better and will use it to hold over his head all the way into eternity.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
