OK, I'm calmed down. Really, I'm so very happy for you...this is a mini-breakthrough....laying on your bed and exchanging backrubs???? Geeeeeez. Sure is different than the silent standoffs you've been having, or when he freezes when you hug him or runs away.
I think it may be that he had a high this weekend, and is finally feeling good about himself. Feeling like you squeezed through by the skin of your teeth with all your effort (his victory at the meeting) must have made him feel great. You mentioned that he needs a lot of compliments and ego boosts. Maybe that's what he needed to take the cap off of HIS emotions, to be brave enough to venture towards you again. He's in a good spot ego-wise, so time to do brave things and really get back the good feelings in all parts of your life--including feeling like a fun husband with fun moments with your W. It's hard to put down that feeling.
I suggest you take it and go! I KNOW it's hard...that's normal. But for now, force yourself to go with it. You've been so patient, your time will come to air your concerns...you didn't wait all this time with such challenges to turn now. Put on that smile and fake it til you feel it.
Remember, you're here to see what'll happen if you really, really try. So go for it. Remember, no expectations tomorrow morning....
