If you are good for each other, that is what counts! A good man/woman is a good person despite the externals that we put much too much emphasis on (and I am no exception......I discount some men too quickly at times)
Well, I believe that nearly all women start out wanting a tall guy... but I've had several short guys for just-friends (in the range of 5'6" to 5'7"), and without exception they tell me that most of the petite women turn them down. Now, if a woman is only 5'1", that short guy is still gonna tower over her by 5 or 6 inches, right? But a lot of the petite women won't date a guy under 6'; instead they prefer to end up with a guy who is three times their size.
The strangest case like that I ever met was an ex-coworker who was about 5'8". She INSISTED that she would not date a man shorter than 6'6". And why?? Because the man absolutely had to be tall enough that she could wear 4" heels and he would still tower over her by at least 6".
This was back when I was about 25 (now 53)... I told her that I'd still be a virgin if I had requirements like that. LOL.
For me, the difference in height still feels weird sometimes. He's built stocky, which helps.
