A 33 year old with a 22 year old? What do you think?

I'm a 33 year old single mother of 2 boys ages 17 and 10. I had recently been seeing (well not seeing, but sleeping with) a 22 year old, who was an istant coach on the baseball team for my 10 year old and also works at his afterschool program. He was (is) fricking awesome, and I miss him, I stepped back from it because I felt weird when he stayed over and my 17 year old greeted him in the morning. I'm in a funky transitional relationship right now with a loser...what do i do here?
