There isn't any cause for worry if you wanna be near with
A. A retains the right to decide whom she wanna hangs out with.
You and A are friends for now right? Are you intending to take a
step further?
Cheers.
I do actually. But B is A's really close friend and listens and
consult her like a mum i guess? Probably B is going to and can
succeed to stop A from going on with me.
