I'm 28 weeks pregnant I'm the only one who drives. my fiance can but not without a valid driver with him. this has made things very difficult he keeps postponing his driving test and it's been frustrating me. I don't want to be the bad guy and out him down. I wish I could tell him how I feel I get home from work a 12-9 shift which is just about every day but one day and he goes in for yam the next day. I want to cry because I get no sleep and I think that's why I haven't been feeling well. when I mention I need more sleep he suggest I sleep a bit before I go into work but he doesn't understand. and when he does have a day off and I get an early shift he refuses to get up with me early and demands he needs to sleep in. I just feel like this situation isn't fair.
