Time for tough love. If you give up all of your space, where is the motivation for him to get back up and fight. Going home to Parents can be a depressing disaster, or it can be a pit-stop on the road. Move some things over, and put a twin bed in for him. That will send the message that you love him, but want him to keep working on his eventual next exit. In the long run, if you make it too comfortable, he may 'give up on himself'. Moving home is a big step back for anyone, but I think it is worse on a guy's ego. No, I am not sexist, but like they say, 'Men are from mars and women are from Venus'. He may even catch 'the addiction' from you. lol!
