I am very frustrated. My boyfriend and I worked on a house for 2 years?

and finally moved in together. He has a 20 yr old son livin w us and i have a 19 yr old son livin w us. My son goes to jr college full time , works at jjc part time. My fiancees son sleeps till 1 or 1.30 pm and doesn,t lift a hand to do ANYTHING. I get so annoyed, all he does is sit with channel switcher.What do I do? He finally just got a 4 hr job. about 19 hrs a week. His dad says he'll do things when hes ready... I am a very active person!!! What do I do?
