Sorry I am a little gasy today and and feeling bloted... It happens on a white castle and skyline chili day... Oh the humanity..
Anyway, Male PMS possibly??? I once had a 4 month break up with the xw prior to getting married. After we reconciled, we would go to parties at "her" friends houses (we were never allowed to hang with mine). I would want to go but not go... I felt out of place and "weird" about it. It would reflect in my attitude. Just a possibility...
Then again, could something else have happened that you are not thinking of...
Anyway, I need to go hit the beano... Thank God for quilted TP eh???
