advice please for a soon to be mom and wife

Background: my fiancé and I are expecting our first child in March and he moved in with me in this month. He is currently unemployed and sits predominantly at the apartment playing video games. When he plays, he usually has these massive sound canceling hand phones on and I have to jump up and down to get his attention (not literally but I feel like I do). He occasionally will cook supper and getting him to clean or do other household chores? Ha! Good luck. He says he is looking for a job, but I don't see it or hear about anything. He gets mad at his mother and I for sending him recommendations we find.

My issue is that he gets mad at me because I get frustrated and upset about doing everything, from chores to bill paying, and at this stage in the pregnancy, it physically hurts to do a lot of what I do around the house, even when practicing proper body mechanics. I work part time, I find a way to pay the bills (with assistance from our families), and take classes part time. He tells me I have to ask him to do things but when I do, he gets mad about it, rushes through whatever and gets back to his games. I just don't know what to do. I've tried talking to him about it and he shuts me down. Him, and doing chores and other means of contribution to the house are my only issues with him right now. He otherwise is very loving and supportive of everything, especially when some drama happened last year in my family (long story short: he was the only one who would help me through it, him and my therapist at the time). I feel like I shouldn't have to ask him to help take care of OUR home. I am scared it might get worse when the baby gets here. Shoot, I might being petty for all I know, pregnancy hormones and all, but it's really aggravating. What do you think and what should I do?
