It'll just be something for her to deal with if you guys separate. Think of all the men that's available for her as potential partners.
IDK if height is a big deal to her but if it is; she has to find someone that is tall with a big dick, that also has a good personality, not a serial killer / lunatic, and that is also perhaps successful and ambitious...that also wants her back as well.
With those 2 immutable physical traits, her dating pool is like a puddle lol.
Now there is nothing wrong with having those standards at all, but she/women like her can't complain when shes old with a bunch of cats saying she can't find any good men lol
