Wife is cheating, am sad but confused?

[HopelessInLove]

Last night spent time with kids at our house and then put them to bed. I spoke very little to W. I did something dumb. She looked very tense and sore. She has also been coughing and not feeling good, maybe stress or coming down with cold. I not thinking (I am still in love with her and don't want her to hurt) went over to her and started to rub her shoulders. After about 30 seconds I froze and she asked me to stop. I froze because of realizing I was not detaching myself. I just am really not in the true detachment frame of mind.

Anyway after that W asked if tonight I would be sticking around after dropping off D from dance. I said I would like that and thank you for offering.

I have been thinking if W continues to say I need to be a man and act like one, should I grow some cowboys and move back into the house and tell her that I will be staying now.???
