So lost on my marriage

This has been going on for a month and half. It started out with me in the hospital. My dad and husband got into a huge fight. My husband refuses to talk to my dad to try to work out there problems and become civil for me. At that same time I was in the hospital have surgery to have a tubal pregnancy removed and my husband wasn’t there. Since then we fight everyday. I have also caught him messaging 20-30 girls a day on fb and have inappropriate conversations and sending sexual pictures. We spent Christmas apart. Then we went on our honeymoon (we got married 6 months ago). The drive to Florida we argued some. Then we were fine for 3 days. On day 4 he got mad bc I cause him messaging girls on fb again. He said it’s bc he couldn’t sleep so he was on his phone. ( I have full access to fb right now) he threw his wedding ring st me and told me he didn’t love me. That whole day went terrible. He finally said sorry. I let it go bc I wanted to enjoy Disney World. The ride home we argued bc he made me drive the whole way (15 hours) bc he couldn’t sleep. Yet for 4 hours straight he sat on his phone while I kept to myself while driving. He didn’t even try to nap. Since we have been home we have fought over everything and anything. I don’t know how to fix this! I can’t trust him. Him and my family will never get along. Please help! Some advice please. I don’t see a way to save my marriage. I don’t want to give up but I don’t know how to fix it.
