Don't stay with the woman for whom you are 2nd best.

I know a guy who is short, smart, funny, ugly in a pleasant way, etc etc and always has an entourage if girlfriends half his age (he is 50+) and 1.5 his height. He likes tall women.

So height or lack thereof is not a problem if you are confident.

Your problem is not that you are 5''2. And, you cannot become taller anyway.

Your problem is that you make sacrifices for people who are not worth it and without collecting enough information about them. That move was a self saccrifice, right?

You must be very bitter now, realizing whom you sacrificed everything for.

But there is a silver lining. This is a solvable, fixable problem. You can learn to act in your self-interest and not make so many sacrifices.

I agree that you are very young still.
