Relationship problems **long post**

My fiancée and I have been together for almost a year and a half, we used to be to loving towards each other and I felt like I was meant to spend the rest of my life with him however, ever since my father passed away last June I feel like we’ve grown apart. I don’t know if its truly because of that though. We were living in Florida at the time and I was bought a plane ticket by my aunt so I could spend a week with my family to cope with the loss. (I was and still am the only one paying bills so two tickets weren’t an option and he wasn’t very close with my father) the entire week I was up in Maine he was absolutely rotten, trying to make me feel like crap for being up here, making it seem like I was cheating on him etc. if I didn’t text him immediately he assumed I was screwing around on him. Mind you he cheated on me with his baby momma at the beginning of our relationship and I’ve been 100% faithful to him. I let him quit his job and ive supported him this entire time, but every week I have to give him my paycheck because it’s “easier” for him to have the money. Weve moved back up to Maine, my family hates him because of everything he puts me through, so I cant go to them for help. I keep finding myself blaming me for our issues and we’ve been fighting daily. I’m sure everyone that takes the time to read this will say the same as my family, but I just feel like I shouldn’t give up on him. I keep trying to make us like we used to be. He’s very jealous, I’m not allowed to even talk to other guys or have them on social media or have Snapchat, but he has a bunch of chicks on his and I can’t say anything about it without him getting mad. He has access to all my social media because he doesn’t trust me apparently and has yet to find any dirt on me. He even deleted one of my coworkers even though he’s gay &married.; I just need opinions from people that arent already familiar with us.
