Recently I had to end a ‘friendship’ as there were 3 of us and one person was jealous that myself and the other person got on well so they did what they could to sabotage us. They were never excluded. I have experienced this years ago in another friendship trio. I don’t know why but I have seen this happen with other people too. Why do some friendship trios have someone who is jealous? It makes me sad they can’t embrace everyone being friends.
