Women are generally shorter than men, so I would expect couples with women shorter than men to be more common even if the pairing was random. There can also be a bias on the men's side - it is not easy to be a very tall woman.

There's a difference between "having feelings" and "blaming a group for not dating (you.)" If someone doesn't want to date you for something you can't change, that sounds like dodging a bullet. Confidence is hot. Being whiny about being rejected is not.
