Why do we change a lot after major life events?

I’ve noticed life events change us or our personalities and we sometimes do things we would never imagine in another reality.

For example, when I was in a relationship I was a bit of a homebody, reading books, writing (this I always enjoyed) and the relationship kind of made me very reserved to the outside world, I wouldn’t imagine I’d be partying this way after break up.

I’ve almost become the total opposite of myself.

My main principles are still with me, but that’s still a 180 degree change.
