If u are doing all this willingly, no reciprocation doesn't
matter. Obviously you expected something in return, and when u din
get it, u r not happy.
She is not right to use u like tat (assuming she is using), but u
shouldn' be helping only cuz e end goal is to have her as a
gf.
Apparently she doesn't make such a good fren either, cuz once she's
attached she don't contact u at all.
This kind of gal is very typical; a lot of bimbotic sg gals are
like tat. Whole life revolve ard some jerk ah-beng. when not gg
well, they are ur best fren, call ya everyday. When doing well or
have other love interests, forget abt u.
Dun bother la, got many gals out there.
