Height is definitely not a deal-breaker for me...Among all the guys I've ever met, there have been a surprising number who made being under 5'4" really, really work for them. Maybe in some cases it's a bit of overcompensation, I don't know, but they really stood out in a crowd, and not in any sort of bad way.
Mr. Jyn claims to be about 5'9", but I'm 5'3", and feel as though when I wear three inch heels I'm not more than a couple of inches taller than he is, tops. And since his height is all in his legs, and he has a really short torso, I am definitely taller than he is sitting down.
The one guy in my past whom I was really head-over-heels about was probably 5'7" on a good day..
I get a kick out of what people consider deal-breakers, though...My mom tells me that her one non-negotiable in a prospective husband was always that he was a good dancer. Given that I inherited my dad's anti-talent for dancing, I guess that went by the wayside.
I was always bound and determined that I would only marry a guy who loved to sing. We have a standing joke that I had always pictured my prospective husband to be a red-bearded Irishman who was an English professor who loved to sing folk songs around the fire at night. I have never heard a note of music pass Mr. Jyn's lips, and, in fact, he gets very resentful if anyone even brings up the subject. Besides which he refuses to grow a beard, which would not be red in any case, and has degrees in math and history, which were always my most hated subjects at school.
My daughter's non-negotiable was height...she was flexible on a lot of personality details, but never could imagine being really attracted to a guy who was not tall. She is 5'5", and her husband is 5'8"
