FBF,
I tried it and didn't like it. It was an "emergency" situation too.
The guy immediately tried to take over. He also acted like he thought that I should clean up after him. He didn't want to share the cost of utilities. He also kept downloading porn and pictures of Hitler on MY computer. He didn't have one of his own.

He also brought guns into the house. When he missed work and couldn't pay his bills, he offered to clean my windows in trade except he never got around to doing more than 2 of them. When asked, several weeks later why he hadn't done them yet, he responded that he didn't feel like it. However, he did feel like downloading more porn. It was a scandal.
When I got onto him about not fulfilling his promises, he chased me to my bedroom to continue yelling at me. I slammed the door and locked it. He tried to come in and when he couldn't, he stood outside my door and yelled some more. I cranked up the stereo to drown it out. When he got back home that evening, he had a note from me asking him to vacate the premises. He did--thank God. I didn't need a grown man in my house acting like a surly teenager.
All he did was eat my food, breath my air and take up a lot of space. He also left hair all over my bathroom. When he left, he tried to leave a 2 litre bottle that he had used to pee in because he was too lazy to get up in the middle of the night and walk 3 steps to the bathroom. I tossed the bottle to him while he was getting into his married girlfriend's car to leave.
I would never have a man for a roommate again. I wish you better luck than I had.
