Search Results: falling for best friend

I'm kind of stuck here. My ex and I were in an LDR and broke up because of difficulties having to do with that. After a few months of not talking, we became best friends again pretty quickly and started to revert back to the exact same kind of relationship we had while we were dating. We agreed on a FWB-type situation for when we can actually see eachother (we go to college 4 hours from eachother), but sometimes it seems like it's more than that. We talk every single day for hours, and treat eachother exactly how we would if we were dating. There are so many more feelings involved than with your average friends with benefits. I know that I'm doing this because I love him and want to get back together in the future, but I'm unsure whether or not his motives are the same. He told me that falling for me again wasn't much of concern just because of how the LDR was unsuccessful (hurtful for both of us when we split) and that he'd be reminded of that if he began to feel something- but he did say he probably wouldn't tell me if he did. Now, I don't know if I should do the same. There's definitely no harm in what's going on right now (I'd actually say it's super beneficial to my life, and also fun) so I don't know if I should ruin it by bringing feelings in it when I've already told him I've moved on romantically (not true..). Should I talk to him about this, or just leave it be? If so, what should I say?
