Okay so maybe I’m paranoid but I wanna hear you guys’ thoughts.

I started a new job last Monday and there’s a guy in his 40’s who I work with.. he has a wife and kids. I’m 22, almost 23. I notice that he looks at me every so often, just quick glances. My boss went for lunch and we were the only two in the store. We were talking, just small talk.. it was fine. He asked me what music I liked, where I lived, who I lived with.. etc. I was doing something in work one day, I can’t remember what I was doing but he told me that I was doing a good job. Then he’d do that ‘smile wink’ thing. You know that wink that isn’t a wink? I don’t know if it makes sense but anyway. Last Thursday we finished our shift at the same time and he ran out of the shop asking me if I’d like a ride home. I said “my mom is just on the way, but thank you so much. I appreciate it.” So I walked into work today, we all said good morning to one another and I started cleaning the store. He was in front of me and said “we’re in at the same time tomorrow so if you want a ride..” I obviously appreciate this but I kinda just replied “well, I’m staying at my partner’s place tonight so he’ll bring me into work tomorrow morning.. Thank you though.” I noticed he didn’t necessarily talk to me as much afterwards.. rarely.
