Women lie when they say short guys arent attractive because they are not confident.
I know tons of short men who are very confident and still has no chance. Just look at dating profiles. 6f or keep scrolling. How does that has anything to do with the guys confidence.
My advice to you as a short men, forget anything women say and watch what they do. Only persue women that has shown interest in you.
In fact that is what most men do.
