Cheater

My husband and I got married in July last year, so we’ve been married a little over a year and a half. Throughout our marriage he has cheated on me multiple times, mostly buying nudes from other females but while he was stationed in Germany (while I was pregnant) he was sleeping with someone there. They were basically “dating”. He gave me chlamydia during that time, which caused complications in my pregnancy at the time. After every time I find out about him cheating he begs and pleas and tells me that it’s never going to happen again and that he’s SO sorry and that he doesn’t know why he did it. When he moved home in March he had a pretty clean slate, I tried to let everything go from the past because we were in different countries and people make mistakes. In August I found out he was talking to another girl. He ended it very quickly with the same excuse “I don’t know why I did it”. I thought we were in the clear after that, although I still didn’t trust him. We argued a lot, he rarely shows affection unless he wants to have sex. Saturday I found out he has a fake Snapchat and has been trying to sleep with my best friend. Who happens to be HIS best friends wife. They called me over Saturday morning after gathering evidence for a week. The “evidence” was all of the saved messages, the dick pictures he sent, the pictures of MY tattoos while sleeping in bed next to him, he was asking her to have threesomes, telling her he was recently divorced, sliding up on her pictures OF HER DAUGHTER holding handcuffs(our husbands are military police officers) making sexual comments like “I could use those on you” and “You look like you give great head”. I left and went home to get my daughter after asking my mom to come pick me up so I could come stay with her. When I got back to our house, I completely lost it. I was so heart broken, I took his phone and shattered it. One of his higher ups came to the house to let him know we were entering a “72 hr cool down” meaning we couldn’t have contact for 3 days, he was to stay in the barracks and I was supposed to stay in our home with the kids. Before I knew what was happening, while I was upstairs packing my stuff, I took a bunch of pills and overdosed. His higher up came upstairs to check on me and found me before I lost consciousness. All I remember after him calling for EMS was waking up in the hospital alone. My husband is now saying everything is going to change and he’s finally admitted he has a sex problem. He has therapy scheduled and is “working on himself”. What do I do next? Do I try and stay? See if therapy ACTUALLY helps? Or do I leave? I am so lost and broken. I need advice. Someone please help me.
