C has a reputation as a playboy, by being in the same sch as C, A is well aware of it.
Most Gals' thinking is.."He is a playboy & he IS INTERESTED in ME...If i can b with him, sure wll b the envious of all gals!"
If their relationship can be easily broken up bcos of minor thing & the gal havin gettin into another r/s so fast only mean tat the gal is not serious in her r/s.
U shldnt be feeling guilty abt it, cos even if u tried to intervene then, it probably wont hav any effect.
& tell ur fren B tat he shldnt even b upset over such gal. Her r/s wif C wont last.
As for C, being a jerk for being so close with the gals tat u guys r interested in....Remember, it takes 2 hands to clap. If the gals aint attracted to his charm & his playboy ways, he wldnt hav get wat he wanted. Those gals arent any better either.
