it dont matter if you not with her. its principals, and that part of the game went stale. not many people value principals nomore. i see dude asnwered this post already so i dont really have to say much, but put yoself in her shoes. how would you like it if she was cool with 1 of her ex's and insisted on keepin him as a friend, against yo wishes? that would make you suspect of some shid and could potentially cause serious issues in yall relationship.
if you had some respect for yo ol' lady, it shouldnt be nothing to chalk that bitch.
