I think only one woman is capable of loving me; anyone know this feeling?

I'm a fairly level headed and rational person (most of the time), but I'm 22 yrs old now and I've only had one gf my entire life. Prior to her, all I have are memories of failures trying to woo women. I think the reason is b/c I'm vertically challenged, so a lot of women, despite my other charms, naturally couldn't endure the public embarrassment of being with a guy shorter than them. My last gf, however, was different. She's one inch taller without heels, and she was more worried about me being embarrassed when we went out while she was wearing heels, than the other way around. We did recently break up b/c of some apparently irreconcilable philosophical differences, and I just miss her so much. Remembering how much failures preceded meeting this one special exceptional woman, I'm quite terrified at how long It'll be before someone like her comes along again. Anyone understand this feeling?
