<human>: I've been with Mike for three months. We see each other once or twice a week (we're both divorced and have young kids), but I hadn't seen him for the last two weeks as I'd been on vacation. 

Last night I stayed at his house and we had sex. We haven't used condoms for a couple of months as I got myself on birth control. This morning he was getting ready for work and I noticed a condom (it its wrapper) on the floor by his bed. I asked him about it and he said, "Oh yeah. Was it by the lamp?" I said yes, and that is picked it up and left it on his bed. He said ok, and when I went into the bedroom later, it was gone. I didn't mention it again, but it's bothering me. 

I'm pretty sure I would've noticed it before, but maybe not. And if he knew is was there, why hadn't he moved it before now? He didn't seem at all flustered by my asking about it, which makes me think it's no big deal. I've also looked back over our text conversations over the last two weeks and he's texted me every night, multiple times from when he got home from work until bed time - which makes me think there's no timeframe for him to have been with someone else. Or am I being naive? Should I ask more questions?

He's given me no other reason to think he might be cheating, although I friend requested him on FB a week ago and he's not accepted yet. Saying that, I have no idea how often he logs on... Should I ask him about this?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Found condom on floor by BF's bed. He didn't seem bothered by me finding it. Only other possible red flag is that he's not accepted my FB friend request.
