I had a crush on my first job in retail back in 1998 - 2000. She didn't work on my department, she worked a few aisles down in a grocery store. I was 21 she was 17/18. Anyway, she never made any effort to talk to me or even noticed me for over 1 year, when onetime she caught me directly staring at her as she walked past my aisle. She gave me a slight smile but I thought nothing of it. I never approached her after that smile. I was like thinking to myself "whatever" "Is she ever gonna make an effort to talk to me? She would of done it by now"
A few months later she maliciosuly said to a work colleague "he's so gay and ugly. And that hair!" at me as I walked past her. It was then that I knew I'm not gonna bother with her. She's not a nice person if shes gonna do that. At the time I had very little confidence in my looks - built like a preteen, very young looking. Had previous abuse from women about my looks. Looking back I could of gotten her fired for slander, but I didn't. Damn I should of!!
Anyway I learnt something - never have a "oneitis" or an infactuation for 1 girl and 1 girl only like i did. She was the only girl I had a crush on for a while, when I should of tried to meet dozens. I was a bit of a recluse and didn't have guy friends to socialize with. Try to meet more people, expand yourself, you'll meet other girls you'll have feelings for.
