Needing advice don’t want to look like an idiot?

I have a younger male co worker I talk with. We exchange smiles, jokes, and have serious eye contact. I have helped him get his swagger back after a breakup, and he has helped me through my divorce. Yesterday I choked up on the phone talking about an issue with my ex husband. He told me I needed to take it day by day, but after I showed that side, we proceeded to text for like 5 hrs and he called me twice which he never did before. Do you think he might have feelings for me?
