She made you a favour not keep in contact. Why would you care about a sh*t head that prefered a 6,3"" tall ugly guy? She chooses boys like meat. If she was minimally interesting, inteligent and lovable, with one inch less than you, she would like to know better about you.
You're simply not short. You're on the average. You won't have problems with girls if you don't fall in insecure feelings or if you don't get obsessed with height and getting "all the girls". Just get to know more, and a bit more sensible than that one. Literally, just let her f**k off. She was simply stupid and void. You were lucky she "left".
