Emotional Affair. Bingo.

Look up the book, NOT "Just Friends" by Dr. Shirley Glass. She devoted her entire career in psychology (almost 30 years) towards the study of infidelity. Her research conclusively revealed that most affairs begin between people that establish an EMOTIONAL connection first. It's NOT (as is commonly thought) about the "hot chick" or the "hot guy". Sex, more often than not, is totally not in the picture.....at first.

And if he's saying he "wouldn't care" if a man texted you...there's already been a degree of emotional DISconnection from him towards you.

Sorry but danger Will Robinson. I hope he agrees to counseling with you!
