I'm not sure how it would effect anything specific to relationships or dating, but at around 5 feet myself, I can't help but still feel like a kid around a lot of people who are significantly taller than me.
I'd hate to sound shallow, but I can't imagine being with someone much shorter or taller than me. I'd prefer someone more the same height. Overall, though, that wouldn't be something that matters in the long run.
