Does he have feeling for me?

I met a guy 1.5 years ago and we have been talking for about a year. We both live in the same small town, but we occasionally hang out (I do know how busy his work is, from early morning till late night).
He initiate conversation on texts, including "good morning" "How was your day" "good night". Phone call is very occasionally.

We actually slept together a couple of times, but he says he isn't looking for relationship at the moment because of busy work also he isn't in the country for several months every year.
I told him not flirting and trying to have sex with me if he prefers staying friends. But he keeps flirting and trying to sleep with me (of course I reject!). He said he doesn't see us as friends with benefits, but I don't think he's serious about me either.

Even I reject sex, he still does his sweet things. He calls me cute, and he said he finds me really sweet and sexy. He gives me very strong eye contact when we see each other/hangout, and rubs my back. His response is always very fast even he hangs out with his friends, at work. He talks about his work to me, tell me his past relationships.

I'm not sure if he has feeling for me but scared/difficult situation of his current life, or just keep flirting then trying to get a chance to sleep with me.
