Do you work? Save up your money so you can find a place and live with a friend. i don't think its a good idea to be dependent on your boyfriend for housing... it should be a mutually dependent situation. As of now though you just became his second mom.. cleaning up after him, taking care of his crap, cooking, etc etc. so stop cleaning up after him, clear out an area just for urself, try to find things to keep you busy and out of the house, and cope as best u can till u get the hell out of there
---oops didn't realize how old this post was... hopefully the OP can give us an update though on the situatioN?
