This issue could be written as a longer topic, but that will be done at a later time. For now, you should know that some people describe themselves or others in terms of "mate value," which basically means how high is a person's value as sexual and relationship material. It might sound weird to others (and it probably is), but that is the way some people think.
Anyway, some people see themselves as being the more worthy mate or part of the relationship, which can be extremely problematic. If a person sees themselves as above you, that means that there is no way to actually talk with them and improve things, as everything they do in the relationship is going to be about them, and finding out ways to make things more enjoyable for them.
