Because Minora is a lesbian. No lol
But seriously she just sounds immature. How old is she anyways?
Personally I think any chick that needs to hide a relationship isn't worth being in a relationship anyways.
That sort of just points out a flag to a bunch of other issues she could possibly have.
Anyways not all girls are like that, but if you're looking for just a slut to fuck, it's not all that hard just most the sluts are usually the ooogly chicks, or the really crazy bitches.
Anyways, long story short, if she's not ready for a relationship it's probably best just to let her go.
