Family Relationship problem

Ok everyone, I think this is the 2nd post ive made about my fiances' parents. His mom is ok I guess. She just thinks that shes dying of every sickness there is. But my real problem is with his dad. He is a freakin' person! He has his masters degree in teaching, but doesnt have a job. He says "he cant deal with the stress." and so he spends his day ordering his 85 year old mother in law around and bugging the caca out of me. I swear he will bother me 30 times a day about some clothes hangers, asking me if I want them. what??? And yes I dont have a job-i dont have a car because the trans is out (i had one but they fired me because I didnt have reliable transportation) anyway..So then he wants to "give me some tips on how to improve my situation." what???? Well then last friday his mom got laid off from her job..She has been telling him for a while that he needs to get a job because she was aware that she could be "let go." I guess he didnt believe her and now neither one of them have a job, and he is blaming her. Meanwhile, she has been busting her rear looking for a job and he just lays around the house..This is what I have to deal with everyday! My mechanic is fixing my car as we speak, so when its fixed and I have a job my boyfriend said that we are getting our own place. His dad says that my boyfriend should now be the one to pay the house payment, utilities, groceries for everyone (he buys ours), and their car insurance. I dont think so. His mom doesnt want him to. Anyone have any suggestions????
