Need to get out on Sundays, don't know what to do

I'm in love with my roommate and he knows it, he tries to be understanding and all but he has his needs. I don't get jealous when he goes out and has sex. I get really jealous only when he brings partners home. He has his own room but being in the same house is intolerable. So I leave the house and just wonder around a mall etc but don't have much money and it's usually a Sunday. Don't have many friends, don't want to date anyone.My ideas for now: (1) Volunteer (2) Work on Sundays? (3) Stay in my room, watch movies and drink beer.Any other ideas?
