Chunchun〜♡ I have a hard time imagining a friend saying 'It's never your fault, is it?' That lacks empathy and compassion at your sense of loss. Relationships are never that simple. People grow apart for many reasons. Maybe you should identify people that do not put triggers out there to be your friends.
Plus once someone like that does push your button, be careful about giving them the power to do that again by selectively telling them what is not going to make you vulnerable.
