Am I overthinking it?

So I slept with this guys a few months ago during a drunken night, anyway we just haven’t had sex but have remained friends by over the last couple of weeks I’ve noticed he is snapping me pretty much everyday or replying more to my snaps to the point that we are each other’s #1 boyfriend, he even complimented me saying I was smart which I thought was weird haha

anyway the other night I asked if he wanted to go out and we did and he got a message from a girl and I offered for him to leave and go see her for sex and he said no, anyway we went back to his and I fell asleep on the lounge and I woke up to having a blanket put over me while I slept... do you think he sees us as just friends? Or does he have interest in me
Am I overthinking it?
