So Lee's response was based on the assumption that the gf is an adult. That was a reasonable assumption.

Felagund23, to avoid unnecessary discussion, you really need to advise us of critically important features of your relationship with the gf. If the gf treats you as her daddy in a mutually consensual manner, this is a critically important and HIGHLY UNUSUAL feature of the relationship that should have been announced in the OP to avoid wasting Lee's time and other people's time as well.

Since you are in college, you are old enough to be aware of the fact that most bf-gf relationships do not unfold in the way yours does, so to the extent that you follow a separate, rare path, you should put your readers on notice about it, upfront.
