I'm 30 and he 43. We met through work and do see each other often. We're not dating, haven't exchanged numbers etc. but he seems interested in me.
He compliments my appearance most times which makes me think he may be mostly just physically attracted to me.
Recently, he commented about when he first saw me at a work do (5 months ago) and said you were wearing such and such. I was surprised he could remember because I had an ordinary winter outfit on.
He has said nice things about my work ethic and relayed positive comments about me from colleagues. And how he's wanted to get to know me sooner.
