So you are deeply, madly, totally in love with a girl who is a bit taller than you. Many men get heebie-jeebies when it comes to the thought of dating tall women. They agonise about what people think and are frightened to smash the alleged social norm of the man being the taller one in a relationship.
Honestly, if this is you, I think you should get over it. The point of dating is to make amorous connections. A person you are attracted to should be someone you follow up with and not dump because of one physical trait.
A lot of men today feel that their dating pool is restricted to shorter women only, and that taller women are totally turned off by shorter men. As a woman, I can tell you that this is not the case!
I’ve always been really felicitous about my height (I’m between 5’7 and 5’8, and I like to wear heels on a regular basis. I really don’t care whether my guy is 5’7 or even 5’6. I’ve actually dated a guy who was a little shorter than me.
The reality is that this myth - that taller women won’t date short guys - is more fiction than fact. Honestly, it’s better off just to not bring up the height difference at all. If she’s entertaining your interaction, or on a date with you, you know she likes you. Its best not to let any of your own anxieties fizz to the surface and make any grounds to doubt you.
Short of shooting yourself up with some human growth hormone, there is not anything you can do about your height. There is a lot you can do about the rest of your body.
To cut the long story short: Tall girl. Short guy. No big! Love is love!
