When will it be enough?

Hello ladies, I just wanted to share my complicated story and see what you all would do if you were in my situation. It’s pretty long but please stay with me I could really use opinions. My fiancé and I have been together for almost three years now, we’ve been planning on getting married in September of this year. About seven months ago I moved across the state to be with him. I left my friends and family to start a new life in his home town where I knew he’d be happy. Since I moved in we’ve had a lot of problems and we’ve been arguing very frequently and viciously (never physicically) basically when things are good they’re great and when they’re bad they’re hell on earth never anything in between. At first we had financial struggles so we argued over that, then it was him always wanting to hangout with his friends, then it was due to the fact that he never helped me do anything around the house or with errands. He’s recently been spending any free time he has playing video games and basically just doing anything except spending time with me. On numerous occasions he’s left me at home crying while he goes out and has fun with his friends and then says I overreacted. He’s always been the sweetest guy and he’s always been willing to do anything for me but for some reason that all changed when we got our own place. He will chose anything over spending time with me any chance he gets and it’s not until I get upset that he SOMETIMES offers we spend some quality time together. He claims he still loves me but for the most part I only ever feel him pushing me away. I don’t know how hard marriage could possibly get, or where you draw the line and call it quits before people take advantage of your love. The wedding date keeps getting closer and I feel like the closer it gets the more he pushes me away. I don’t want to make the mistake in marrying someone who doesn’t love me, but I also don’t want to make the mistake in leaving the person I think is the love of my life and I’d give anything in this world to be with. Is this temporary?? Is it normal for couples who just moved in together to have this many problems?? Had I married him before moving in together I’d have to deal with this and figure out a way to get past it so what makes it different if we’re engaged??
