It sounds like you are doing great. It must be so hard to keep the R talks at bay when he is the one bringing them up. You are right about probably being the only one on the board with that problem. I have to stop myself from R talks not stop hubby. You are doing great though!
I think you have a good idea of what to do next too. Take some space tonight since it sounds like the two of you will be in close quarters the next day or two?
Remember not to read too much into his tone and attitude during this trip. Making assumptions about his mood or what he is thinking or feeling will only get you in trouble. I know how hard that it, believe me, I struggle all the time with battling the voices in my head saying "he's annoyed with you, you're bugging him, he doesn't want to be here with you, etc" It will only make you crazy. You have to learn to turn it off or at least turn it way way down.
You are not on trial. Please try to remember that. Even if you really feel that way try not to dwell on it because it will only make you act on trial and you will not be acting like the real you. Which your hubby will pick up on and will become suspicious of your actions and attitude. Just be careful. Don't be fake or overdo it. It's a fine line.
Again though I think you are doing great and if you keep it up I think you should start seeing some changes in your interactions with him.
I did want to ask you a question. After his comment about having not wanting to sex with you are you inclined to ML if he offered or initiated? How do you feel about all that right now?
Keep up the good work dear! Try to relax and breathe it really does do wonders!
