Is it wrong to flirt with my son's friend?

My son is a junior in college and plays hockey. His best friend is also on the team and I see him occasionally at the games and a lot during the summer when he comes over before a summer league game or a dip in the pool. He asked for my number because he said he was in charge of creating the roster and schedule this year and I gave it to him but he has been texting me to say hello and chat a little. I can't tell if there is a hidden motive but I don't try to stop it. I dont know why but I can't ignore his messages
