<human>: Me and this girl have been "talking" for a little bit. Recently she told me she was into Collaring, In lamens terms she wants a Master/Slave relationship, her being the Slave and me being the Master. I'm fine with this and I actually made her "mine" last night. However when I asked her to actually be my GF she didn't want it but said she would stay faithful and not talk to anyone or do anything with anyone except me. I know it looks bad, me being 18 and her being 16. I am confused and concerned that I am going to get hurt here. It sucks.

Can you summarize the given text in a few sentences?
<bot>: Girl says she wants to stay faithful but doesn't want to be officially in a relationship. I am concerned I am going to get hurt bad.
