My ex did tell me I’m shorter than she wants her bf to be. I was still talker than her by 2-3 inch but she wanted me taller than her in heels. And suggested I do exercises to get taller.

I ended it with her soon after that. I think if someone has thought like that, there are other common patterns that makes the relationship too much to worth it. My wife now is same height as me and we’re happy about that, height difference of several inches seems weird/difficult to imagine now.
