Old Coworker

So I used to work at a business but quit earlier this year due to mental health and the long hours I was given as a college student working until 5am.

Anyway…I was 18 at the time of working there and turned 19 when I quit. I’m almost 20 now and he’s almost 30. I began liking him after we would spend long hours at work together working alone, and would just talk since we were the only two there. Nothing ever happened but I started liking him for who he was.

He has a kid, he’s almost 6, and got divorced right before I quit the job. We’ve stayed in contact since I left and I saw him a few nights ago when he brought me some soup because I was ill. That small gesture brought all the feelings back because I had suppressed my feelings over the summer. WHAT DO I DO?? Do I tell him how I feel?
