is he falling?

been fwb with this guy that I work with off and on for 3 years now stopping every time I get a boyfriend and resuming after him and I break up. we just started our fwb relationship back up again about 3 weeks ago but things are different this time. he likes to hang around and cuddle after sex, he texts me every day (nothing sexual either like.. just to talk), he introduced me to 2 of his friends, he tells me to look at him while we are having sex so he knows I'm thinking about him, and we just planned a trip to Detroit (10 hour drive) to see our favorite singer on new years eve. can someone tell me what's going on lol
