... okay here is a funny story you can laugh at about why a relationship didn't work out. I'll try to spare you some of the details.
Due to an anterior pelvic tilt along with other bullshit I was 172 cms tall (with proper posture I'm 178 cms, around her I probably fixed the posture because I didn't even notice the height difference). The girl was 183 cms. She was a party girl with a bf for 5 years (but he didn't want kids, he was 30+). She wanted to change ship but she wanted me to change my hobbies and she complained about how funny we looked. She thought very highly of herself just because of her height. So I tried to let her down easily (because I'm neither going to change all of my hobbies, way of life, become an extrovert nor will I grow 10 cms). She went berserk and we stopped talking. After a few months she tried to communicate again with me again but let's say her opener was very bad. The good thing is she later found a guy her height and she has a kid now.
So imagine this, 5 pitiful cms can get you this amount of bullshit. And that's from a guy that is INTO taller girls (once covid is over I'm heading to watch women basketball).
