Pregnant and depressed.

I moved away from my family to be with my fiance. I got a job down here. I moved my kids down here (thank god none of them are in school) and now I feel like I made a big mistake. I feel like I dont belong here. We are currently staying with his parents until we get our own place. But that seems impossible when hes always handing his mom money for pointless shit. He has a way better job than I do but I bring home more money than him (due to him having a loan for his truck and a snowmobile). I talked to him about getting rid of the snowmobile and oh no he cant do that. But here I am working double shift at a fast food restaurant so I can save up for us to get a place. I feel like I'm doing everything and hes doing nothing..I get up in the middle of the night with our daughter (even on his days off I still have to get up with her)...I cook, clean, and take care of the other two kids with no help. At this point I feel like hes just an extra body that I have to take care of. I miss my home and I want to go back.
