<human>: Can you condense the text into a few key points?

I work as a receptionist at a gym, and most of the younger male members are very friendly with me. One guy [28M] who would always stop at my desk and chat recently broke up with his girlfriend about three weeks ago. She also attends the same gym. I just split with my boyfriend as well. As soon as this guy finds out I'm single, he asks to hang out.

We end up hitting it off and decide to have some sort of friends-with-benefits situation because we both had just stopped seeing people, his ex still likes him and we're both in contact with her, etc. We started "seeing" each other last week. Today, out of the blue he texts and asks "What if you fall in like with me?" and I replied "Why, are you worried about that?", and he replied "I'm not worried."

We call each other "floosies" as a nickname because of our casual fooling around, so I texted back "What, you think floosies can't have feelings?" and he said "They might :P"

I don't know what he meant by this. On one hand, I am weary of having another relationship right now, but on the other, we get along great, I like him and I don't want to rule it out in case I do fall for him. What does he mean?
<bot>: My friend-with-benefits said he wasn't worried about me falling for him and I don't know if he meant that he already has feelings for me, or if he thinks I just won't develop feelings for him.
