Guys, Where is his head at?

I have been having a casual ‘situation’ with a guy who is in a relationship. Not great but it works as I don’t want any type of commitment and he’s not able to so it’s purely sex.. although we chat everyday and he calls me throughout the day and every evening on his way home. He is the one that has initiated the extent of our talking and I’ll admit I enjoy it, we have the same humour but I don’t know where his heads at - he will get annoyed if I make jokes about us not talking (as in ‘you don’t have to call me everyday’) but I know if I asked him where he’s at he would be insistent that he’s just using me for sex and has no feelings
