Very interesting question lola…Were our spouse programmed for this?
I remember being at MC with my H (the 2nd of 2 times we went)and I told the MC that I still loved my H. His behavior isn't reflective of who he was. I told her that I would never have expected him to cheat. He wasn't the cheating kind. My H corrected me...and said "I cheated on almost every girlfriend I ever had- this was my longest R before cheating". Hmmmmm??!! My H left that out of all of our preM conversations. He just said the R died...or it was over for some time- but up until that point..he never told me that he cheated on almost all of them.
I don't think I believe "once a cheater..always a cheater"...but I wonder if it does become easier after the first time...then the 2nd time...etc.
