This is such an interesting question because I'm barely 5'1' and I'm really like this guy that is around 6'6"! Height doesn't matter to me. It's everything else before that. I'm short and I know it, but if the guy doesn't care about me being so short, I shouldn't be caring about him being too tall. I would totally date him, ESPECIALLY if he's a gentleman and is caring and sweet. Height shouldn't come in-between relationships and love. Don't worry, relax, it should be the least of your worries.
I'm 5'0" and height doesn't matter to me in a relationship. If he is way taller than me I don't care as long as he has the qualities that I'm looking for. Wouldn't bug me one bit, I actually know someone who is shorter than me, but her husband is 6'5". They make a great couple, personality matters more than looks and what's inside rather than outside.
