My anger with those that I care about but who hurt me is vindictive, how do I fix that part of myself

Didn't think I'd admit that. But okay. Maybe I should talk about it at least. So. What I've noticed is that when I'm angry my aim is to burn bridges. And when the other person reaches out again despite of my actions it becomes a thorn in our relationships.

When I say I burn bridges I mean it - I bring up the shit they've done in the past , or draw a meaning from their own experience which suits my analysis. I paint them a shitty person. The fact they might be or might not is a different matter.

But I do do that.

How do I fix this part of myself.
