There might be some rules at the school about not getting involved with the parents....so go back to the bike store, start a friendly conversation about anything...then ask him if he's spoken for or single...he might ask why, he might even say he has a girlfriend or maybe he'll tell you he is single or still going through a divorce..what ever his story is, you'll know if you still want to get together with him or not..
Then say, "I couldn't figure out if you had a women in your life or not...and I was just wondering if you were legally free and not spoken for, would like to meet for coffee or have lunch with me sometime. ((((don't use the word "Date".)))))
Suggestion: don't date anyone who's married or hasn't been legally divorced for at least a year....It's nothing but heartache and trouble. You deserve someone who has their act together. Someone who's mind isn't else where when you are trying to spend quality time with them.. These people think they can give you the moon but they are just way to screwed up to do so...
Join different local activities that you will enjoy doing...it's the best way to meet someone with the same interests..
......and learn not to take rejections personal. Most of the time rejections have nothing to do with us although we do feel them that way...it's just a feeling that will pass..it's not the end of the world. Everyone's situation is different....Some people are shy, others can be nervous, lack of money, not ready to date, lack of time, health problems, stress, not free to date, or just don't want to date, etc...
