Don't you believe that you are worth more than this? Don't you believe you deserve more? He is a serial cheater or a multiple cheater and you have be S for two years. He's got just what he wants. Why do you think he is going to drop two or three women and go back into a faithful MR?
As long as you live in the land of "hoping he will change"......you deny yourself of a fulfilled life. If he was evaluated for H material, do you really think he'd pass? Give yourself a big gift of dropping the rope and go get yourself a life. ((Hug))
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
