Roommate/house guest

So my husband and I took a friend in over a month ago... he has been a great house guest. He cleans the dishes after every meal, keeps his stuff put away, and helps me around the house. The problem is that we can't afford to feed and clothe him for too much longer. The baby is due June 6th, and I need some alone time and time to prepare for having someone that needs my constant attention. He is constantly talking to me and wanting my attention, and I can't keep doing it...
