<human>: Edit: got to include years. My BF and I are 25, not sure how old my friend is but I'm guessing 29.

**Me and my OH:**

My boyfriend and I live in a rented house with a spare room, I have had sharers here in the past but we've been here alone for a while and we like it, we're going to be moving somewhere smaller and closer to town this year.

**My Friend:**

I have known this guy for about two years, he's very sweet, and intelligent. I've always thought there was something a little not mentally present with him... But also the feeling he's completely harmless. Whenever we've met at social gatherings, or I've met him at the pub a few times, I've been supportive on his dreams and ambitions. He's a great musician.

The time I have known him, he has lived as a lodger in places and it hasn't ever really worked out - it's always been temporary, so he's constantly looking for new places to live. So last time I saw him (which was late november) He was happy to tell me he was in a new place and enjoying it, which was good to hear.

However, out of nowhere he's been texting and calling today saying that he's got to leave his room TOMORROW because of a 'complication' and he was wondering if he could stay at my place for a week, and that he'd pay rent for it.

Thing is, my OH isn't back until Tuesday (taking a trip to see his family) and I'm in the house alone, I don't feel that I know him well enough to put him up for a week - besides I've been burnt in the past with people overstaying their welcome and trashing previous shared and rented homes. I am wary... But am I being selfish/mean for not giving my friend a chance?

I haven't replied to any of the texts yet.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: friend wants to stay at my house for a week, I am worried that he might overstay the week/create problems. Am I being overly cautious?
