Always accusing

So my husband & I  We got married Jan 2015, only lasted 6 months, got a divorce in Aug, 2015. Once we got married things changed, he changed it seemed like once he got what he wanted he changed. He's in the military, he was stationed in Cuba. I think distance had a big part to play in it. I did some things once we were finally divorced. We talked it out, over came everything & started dating again. Over memorial weekend this year we got married a second time, he told me he didn't trust me & it wasn't going to be easy but I still agreed to marry him. Now all he Does is constantly accuse me of lying & cheating to the point Its draining me, physically, emotionally & mentally., I'm always proving mySlef to him. Sending him screenshots of my call log/messages. I agreed to let go of my social networks (FB, IG & snapchat) he has a key to my apt (suppose to be moving in together August 15) I'm always on the phone with him or always txtn. I can't have female friends,. I have 2boys from a previous relationship, when I do talk to their father about our boys he gets so jealous & tells me that maybe I should get back with him,. It's like so much going on. He's constantly breaking up with me. He says he's this way with me Bc of what I did in the past, I never cheated. Idk what to do. I love him & I want to work tho had out but it's like I'm putting mySlef in a dark place. Any advice?
