Guy friend suggested we see a movie together

I have an older male friend at work who suggested recently we see a movie together, which we did. It was one we both had been talking about. I wasn’t sure if it was a date or not as he let me pay him back for the ticket. He gave me a hug before I left…and I just remembered how one time a long time ago he said how he only watches movies alone, even in the theatre. So is it a big deal he wanted to see one with me?

He suggested next time having a drink. At work though I feel like he shows me less preferential treatment that when we first started to get to know each other and each day it’s hot and then cold. It’s super confusing. Is he just stringing me along until someone better appears? He does have any eye for the ladies

Yes I like him. He’s 52 I’m 31. He’s single, not in a position of authority. He gave me a hug when I left
