Coworker/Friend.

So to start this off I am 19 and my friend is 32. I look at him as a good friend and we went out to eat at Ruby’s Diner and after that went to see the movie The Escape Room. This was about a week ago , I had a good time. Ever since he’s been taking me home or going out to eat on our lunch break or after work... So yesterday when we were at work on our break we were talking and he had mentioned that someone said we’ll make a cute couple. When he had told me that I’m like what .. then he says that he would give that a chance if that does happen. But the big age gap gets to me.. I had no words to say to him when he told me that , I was just so stuck on what to say.. he apologized for making it awkward though. Although he says I’m good being friends and keep it this way. I just don’t know what to think right now .. I mean it’s a little awkward for me but not really.
