Oh uh uh..you are living my life girl. Run while you can, there is always a way. My ex resented my children and even had the guts to tell me so. I went what you are going thru with my hysterectomy years ago. Run like the wind, I wanted my kids childhood to be remembered with a happy home. I loaded all three kids in my van along with all three labs and drove off leaving him sitting on the front porch of that big ol' house saying "You aren't going to leave this checkbook!" Watch this mother f!!!!! As we hit the highway back to Texas we simultaneously screeched with joy. Aw, it was great! Life has been a lot slimmer since but my children had a happy life...all worth it.
I will pray for you. Please take care of yourself, your are worth much more than this.
