I think I fell in love with my sex buddy?

I often sleep around to be honest. And this time my sex buddy is someone my age. He is 26. We work in the same company. But he is an engineer and I just sell food. So he is very much superior to me. Yesterday he asked me to come over because I had some minor problems in my apartament and he suggested to not go to a friend but spend 2 nights at his place.
I heard him talking on the Phone with someone about an unnamed girl. I dont know the context but he said " thats the kind of girl you take home to mum"
I asked him in a "joking" way what kind of girls one takes home to mum. He just said "not all girls should be taken to mum"
Nothing else.
I dont know if I have feelings for him. He is very intelligent, charming, handsome and never disrespectul. Should I tell him I like him? He invited me over for my own confort. To be closer to work. Maybe he cares for me?
