Search Results: keeps a guy''s interest

I met him in high school. I had a crush and we were friends but he didn’t seem interested. Then suddenly, randomly one day he did, I don't know what happened. He invited me to his prom, he was super chivalrous. We went on a few dates (this started towards the end of us being in high school and carried on into the first year of being in college) he treated me well but I didn’t feel a spark. He paid for our food or whatever we did, and I enjoyed his company but didn’t see it going anywhere. I didn’t wanna hurt his feelings but I couldn’t keep seeing him, especially with him paying I wouldn’t wanna take advantage of him. Anyways I got to the point I just made excuses when he asked to do something cause I was afraid to hurt his feelings even though I probably did regardless. Eventually he stopped messaging me and we haven’t talked since. I’m s few years wiser now. I can look back and see he treated me MUCH better than the guys I’ve been with since. I knew at the time he was such a good guy and I was so mad at myself for not being in love with him, I should be. Any girl would be lucky to be with him. Anyways, I wanna reach out and at least apologize and maybe give it a another chance, if he would even give me the time of day. I’m nervous too though, and I’m nervous to give it another shot and still just not feel any thing and potentially hurt him again, although this time around I would give him an explanation instead of just ghosting. Should I give it a shot or leave it alien?

Guy found out that I liked him through friends and seemed to be interested but never approached me. Now seems genuinely interested in another girl and flirts with her but after catching me looking at him once he keeps secretly glancing at me when he thinks I’m distracted. Why?
