What if I ask my wife not to sleep with other women?
I can understand why you wouldn't want her to be having sex with other people.
Having my wife sleep with other women is really disgusting and makes me feel bad.
Your wife shouldn't be sleeping with anyone else in the first place, much less women. If she continues sleeping with other people, you may end up growing apart and eventually divorcing.
It's not my fault she's that way. I want to stay married and to prove that I'm the better man.
Do you really think you'll be happy with that arrangement? You should consider couples counseling, because I don't know how much longer your relationship will last on its current trajectory.
