Cheating husband? Is there ever a turning point?

I have known m husband since I was 15. Married him at 19 and have now been married for 5 years. He has always talked to other women behind my back up until I ended up pregnant with our daughter 2 years ago. He swore he would changed and I believed him because everything went well during my pregnancy up until I gave birth. 3 months after giving birth he had a profile on multiple websites that are only for hook ups. I found out a few months later on accident & I confronted him. He again swore that he wouldn’t do it again, but then I found that he continued and apologized. At that time I felt vulnerable because our baby had just turned 1 and we moved away from our family to another state. Our lease was up and I told him I wanted to end things and that I wanted a divorce. He begged to stay so I gave it another chance. He started going to night classes for the automotive program. He started staying late and “hanging out with friends at car meets” every Tuesday and Thursday. I didn’t want to feel like I was controlling him so I didn’t make a big deal out of it except when he started coming him at 12 AM. Just 2 days ago I got a feeling that something was going on so I went through his phone. I don’t see any suspicious text or any hooking up apps. I decided to go through his pictures & found two screenshots of him talking to someone about anal. The text went like

Her: My butt still hurts. I feel like I can’t shit anymore

Him: so no more anal

Her: that’s what happens when you do things unprepared

I woke him up immediately asking who it was that he was cheating with and how did they meet. He told me that it was some girl at Walmart came up to him about how “cute” he was and started texting. Supposedly he said that he never cheated and that she was talking about how she had anal with another guy because she’s into extreme sex with her boyfriend and other men. I told him we were over for real this time. That I was going to file for divorce because I couldn’t do it anymore. He told me he seeks attention from other women because I’m too good for him and that he knows one day I’ll leave him so he wanted to make sure he had something lined up. Immediately he deleted every girl he had on Facebook and instagram, shared his location and started posted pictures of me and our daughter something he had never done. Last night he came home with flowers but I rejected them and made him sleep on the couch. I feel manipulated and broken because I love him but I’m not in love with him anymore due to all of this BS. I want to leave the relationship but I don’t know how because both of our families live in Texas and I want to be with them instead of California where we live. He doesn’t want me to move and said he would fight for custody. I have my own job and I work full time but I don’t have anything in savings because he took my money to start up his career. Something he promised to pay me back ($8,000) but I know I’ll probably never see any of it again. I feel broken, deceived, and without options. How do I find the strength to stop loving someone who does nothing but hurt me?
