I hope someone will respond to this updated post.

I am still trying to work through this relationship problem with my W. I thought we had a great Easter weekend. She actually gave me small kisses on the lips the last two days,which I interpreted as a thaw.

Last night she worked out with her Trainer(the same one as above. After she came home she spent the next 2 hours on the phone about work related problems. I understood the need to do so. I just kept reading Divorce Busting(great book, by the way).

The strange part was after we went to bed. I have been falling asleep fast due to waking up ever night, running our situation through my head. Last night I did not fall right to sleep. To my surprise, I could tell my W started to masturbate--something I have never known her to do. I stayed still, but when she was interupted by cat jumping on bed, I touched her arm and said ILU.
She just told me to go to sleep, then went "back to work". She was quiet--I couldn't say if she was satisfied.

I obviously a not offended by masturbating--I've definitely done it. What I don't know is how to respond now? Obviously I knew what was happening and made it that she should know I was aware.

I doubt she was fantasizing about me--more likely the trainer. She had told me he was particularly nice to her last night(had cancelled on her last minute twice recently). Do I say anything to her today about last night? Do I forget it completely?
