ive been seeing a girl for about 2 weeks now, and was wondering when it is appropriate to talk about her as my girlfriend and vica verca? as this is my first relationship i actually care about i havent ever bothered to wonder about this before.

As her if she considers herself your girlfriend. If yes, then you can refer to her as your girlfriend.

Just don't worry about it, let her bring it up first, just enjoy the time you spend with her.

i say u should giv her some signals. lets see how she takes it.
