Is this groundhog day? I feel like we've been over this with you. Again, you ARE over thinking everything. Please remember to take some time to enjoy the moment instead of thinking about "What it means?" As Sigmund Freud said, "Sometimes a cigar is just a cigar." You have got to stop trying to read into everything she does. It's driving you crazy. The bigger problem is that once you back on sound footing, you won't stop doing this.
The only one who is making it a game is you. Do you trust your wife to tell you. If you aren't pacing correctly? You've been with her for 21 years and you are saying you don't know how to read her?
I know it's easy to get frustrated at the pace of things, but geez it's only been 30 days since the OM was in the picture and you are trying to jump back to where you were.
I'm curious if are you guys in MC? I think it would help to find one that would work. Maybe your W could say things in the sessions that reassure you. Like I said, the fact that she doesn't pull away might be more meaningful than her saying ILY right now. The fact that she spoons with your is probably more important than eating ice cream nude in bed with her. Those are messages from her. You have to appreciate what she is willing to give you now with the hope that that isn't all she can give you.
Patience is bitter, but its fruit is sweet. --Jean Jacques Rousseau.
