If you think it would be too difficult to have him living with you for a week, as only a friend, after growing close for 8 months, I'd be honest and ask him to make other arrangements, at least when it comes to where he sleeps. No one could possibly know what's truly going on in his head, but him. It seems like a game. He could be afraid of comittment. He could just want some light fun without any responsiblity or accountability. Maybe he's involved with another or others. Maybe he doesn't feel the same way as you do. It's so difficult when relationships get complicated and you end up playing guessing games as to what the other really means or wants. Don't go there. As hard as it is, stand up for yourself, for your needs, and what you can accept.
