How do INTJs deal with Breakups?

Personally, I've always had an avoidant attachment, and also learned to detach from situations quickly.
If broken up with, I'd just coldly agree and never talk to them again.
If I was the person doing the break up, I tend to create mental distance first to make the process a little easier (emotionally).

I'm just curious what everyone else is like when it comes to romantic separations
