One I dated for a few months, she was very blunt and made me compare heights with her. She put on heels, measured heights again in my lifts, and said "well, at least you're still taller." Shortest woman I dated at 5'2", but the most sensitive about height (definitely a correlation there).
Another was much kinder, we went on several dates. She shared how her mom decided to date her dad, one of the major factors was because he was tall. She quickly added "not that it matters, it's very silly." When the lifts came off, she didn't say a thing. When we were putting our shoes back on to head to dinner, she said "I might be taller than you if I wear my heels." I said it's OK, doesn't offend me. "Oh no, I didn't mean to suggest that!"
I brought up my height a couple times, and she picked up on it. She said she has a friend about my height and he's concerned about it too. She told me to just be more confident. We're still in touch, it'll be interesting when I tell her that I bought my confidence. She's 5'3".
Another woman I dated for a few years; I didn't wear lifts at the time, but she told me during the beginning that she usually only dates tall guys. Maybe it was a compliment in a way, but it didn't feel good. She would make jokes about how if things don't work out she'll find "Android 2.0," a taller (better) version of me. She's now one of my best friends, and is 5'4".
As for my taller former girlfriend, we started dating end of high school and through college. She never mentioned my height in a negative light. I got to escape the feeling of rejection for many years, which is why I'm a height neurosis late bloomer; I'm lucky that I didn't need to stress about rejection back then. She was 5'7", entire family except her mom were giants.
