bro, there really isnt anything you can do about it. we have a similar situation, but a little different lang. akong girl bestfriend dili mubiya sa iyang uyab na abusado kaayu (but not the physical abuse ha,) bisan more than 20 people told her to leave him, wa gihapon.
wa kay mahimo, you'll have to wait until she realizes that toxic iyang gihimo. tagam ra na xa. ust keep watching out for her lang, simbako naay mahitabo niya.
try cornering her and telling her everything; dont
talk with her, warn her. doenst matter if she wont listen, just tell her that what she's doing is wrong, and that the guys i toxic. tell her that you're still gonna watch out for her bsag di xa ganahan, but youre not gonna meddle anymore. after your're done talking, ust shut up and walk away. no romansa, ust straight, hard, truth. i hope mas swerte ka nako. gudluck bro.
