Most of your exes getting engaged and married.
It has you wondering, "did I make a mistake?"
If you did anything different, could it have been you marrying one of them?
You know what else could have happened?
You could have gotten engaged and married to the wrong person.
Stop looking at people's life events and comparing your personal things with their public things.
Maybe the proposal is better than the relationship.
Maybe the wedding day was the only good day in the relationship.
It's better to wait on your turn.
It's just not your time.
Your love story is still being written.
