Problem by @Psychotixs

Wow . First of all , that guy is a jerk . Ignore him .

He is probably trying to rub it in your face that he had moved on and is back to annoy the crap out of you . Its really funny how he managed to get along with your friend whenever you guys are out together , making you look like the third party there .

In any circumstances that you feel like an extra and unwanted , just tell your friend that you aren't feeling well , or if you feel bad for lying , tell her the truth about how you feel around him and that you want to leave first .

Let her know that you arent happy and fine when he's there to laugh at you for liking kpop and dying your hair . Maybe your friend could persuade and tell him to back off . You will never know ?

If hes really abusive , how about talking about it to your friend and also notifying an adult ? In this situation , violence should never be allowed no matter how the two of them fought . If shes getting worried and depressed over it , it meant that the relationship is toxic , and therefore you should tell her to break the relationship off .

You can slowly distant yourself away from your friend if you are uncomfortable and dont want to associate yourself with the guy .

You cant control your feelings — or your friend's . At the end of the day , it is still up to her to decide herself . Just be there for her whenever she is ready to spill anything to you . Comfort her .
