FWB behaviour...?

I guess he is a FWB, but it seems more than that. We hang out a lot but don't sleep together every time we see each other. I was showing him some photos in my digital camera, and there was this really cool one of me and he asked if he could have a copy of it. I printed it out and gave it to him a few days later. It now sits above his TV in the lounge room! He worries about me, I had a minor routine procedure at the doctors the other day and he was so worried, he called me as soon as he could to see if I was okay, when I hadn't even made a big deal out of going to the doctors in the first place! He also worries I'm not eating enough, and invites me over so he can cook for me because then he's satisifed that I'm eating, the right things! Is this typical FWB behaviour? I've never had a FWB before!
