Friends with benefits?

I have been hooking up with this guy for over a year now- and we’ve became really close since we started to HU. Now all of a sudden he’s kissing me goodbye and giving me multiple hugs before he leaves and is being really touchy with me. He tries to give me hickeys and I tell him not to bc my job. He’s now starting to ask if I’m with a guy / or who I’m with when I’m not with him?? And if I’m hanging with another man he’ll get upset with me?

Does anyone know what he could be thinking?
