Being short means you are hugely attractive to many guys. I prefer girls to be under 5' and a few inches. I doubt very much you are remotely ugly, as he would not have wasted 6 years of his life. He is just using it all as an excuse for leaving.
Put it behind you, and find one of the many guys that will truly love you for being you.

what? that's so mean that he would say that to you, you have to realize you are wonderful no matter what he said or anyone said. You have your own uniqueness and you have your own gifts to give to the world. Just move on from that guy, he's giving you toxic air.
