I have three best friends at school. One of them plays Fortnite and the other doesn't (but I don't play much). A few months ago there was only a fight between them and the two suppress the one who gambles hard, I just told you my opinion and then you became friends with me terminated. At least I wanted to team up with the one who plays Fortnite, but that's all over with them (she has severe family problems and has not wanted to talk to me for weeks).
What should I do now? Are you looking for brand new friends or visiting the other two again? Or are you still trying to stay with the gambler?
Hm, you are really in a difficult situation!
I advise you to wait and not jump to conclusions. Talk to your gamer friend or at least give it a try. If that doesn't work (which you already said yourself), you can try to make friends with the other two again. First of all, apologize to them. Maybe something will come of it.
Only in an emergency, when you really feel abandoned and neglected, should you consider making new friends. Everyone should be given a second chance!
