I need hope

Summer
My husband cheated on me while I was 26 weeks pregnant, and decided that he loved the other woman more than both me and the baby. I had to go through the last 15 weeks of pregnancy alone and super depressed, because my life as I knew it was forever gone. Just a fantasy. My baby would grow up in a broken home and I couldn't do anything to fix it. 
We have been going my through a rough divorce...he keeps doing really really mean things...sneaking into our home while I'm not there to steal my stuff, buying a drone and flying it over my house, lying and stealing money, bad mouthing me to everyone, even though he told me his only reason for cheating was that I didn't have sex with him enough...
When the baby was 3 months old he decided he finally wanted custody. He filed a court order and now has her for 10 hours a week. He refuses to say a word to me when he picks her up or drops her off.
My question is...have any of you ever been through anything like this? What ended up happening? Did he ever give up? Did karma bite him in the butt? Did the other woman end up staying with him? I need to have some hope that this nightmare will end soon...
