If every friend group ends the same way, the common factor is worth an honest look. Kindly, but honestly.

When the same ending keeps arriving, it gets harder to read as coincidence. That does not make you the villain of every story, and it does not mean the other people were blameless, but you are the one constant across all of them, which makes your own part the piece worth looking at. Honest and harsh are not the same thing.

Think about the last couple of friendships that ended and look for one thing you did in both. Ask somebody you trust whether they noticed it too. Then change the behaviour rather than your verdict on yourself.
