Just need to rant

Sorry I just really need to rant. I'm 32 weeks pregnant and tonight my back is killing me and yet every time I ever ask my fiancé to rub my back or anything to help me feel better he says he doesn't want to and it's getting on my nerves tonight I can't sleep because my back hurts that bad and I tried to sit up and I had to get him to move his head so I wasn't suffocating him because our bed is only a full and feels super tiny with two people on it and he flips out on me for trying to move his head out of my side! I just want to cry and yell right now 😡😡😡😭😭😭
