Your H just told you that the OW was not grilling him...did you listen to him? No...you kept on asking more and more questions...please, stop it...you are talking your M to death.
The point of DB, again, is to put yourself in a better place than you are in now...that means taking care of you. Stop analyzing and wondering what he is doing and needing him to promise you his return...you are nagging him to death.
You are overbearing...we all see this. Yes, you pushed him into this affair...it took him time to start it...now you have realized your mistake in not taking care of his needs. So, you're ready to be the love queen....sorry, but he does have feelings for this other woman. He's not just going to toss her aside because you demand him to do so.
Be smart...he will end it when he feels it's the right time to do so...the more you keep bringing it up, the more she seems ripe to keep. Think about it...would you want to come home to 20 questions, desperation, and a scared man? No, you wouldn't.
Everything, AT, Whatis, Heywyre and I have told you is what you must do. Read the whole book...you'll see that there is more to your problems in your marriage than just the sex.
Give your H some rope...don't try to backoff...you must do that immediately. Quit asking him questions, don't talk about the R.
We are here to help you...we all have been through this, or still are in the process...
We know you love him, don't want to lose him, but the path you are on is pushing him into her arms further and faster. We KNOW exactly what you mean, that's why we are telling you to do the exact opposite of what you feel you want/are doing...it's called a 180...it works, also detaching from your H will bring him home faster.
