My mom's friend was flirting with me?

I was at this party in my house and one man (my mom's friend with she used to go to college) start to talking to me i was really chill but then he ask me about my boyfriend and was telling me how mature i was and in a moment he licked his lips while he was looking at me, so i just smile and left haha.
He was flirting with me or it's all in my mind?
