I know am not a girl, but my boyfriend is my sex partner.
Make a move to be her boyfriend trust me im a girl i would know.
If she's taken, shes taken.
No you should get to know her first! She might get scared away because you barely know her and she barely knows you..
Facebook...
I don't know. Talk to a therapist.
buy him a bacon sandwich
You should tell the other girl and both break up with your boyfriend.
She likes you.
ask her
introduce yourself and say hi, get to know her.
I would say she is trying to make you jealous, or that she wants everyone to know she has the greatest boyfriend in the world, and she wants the world to know.
