How to Deal with Ugly Feelings

I read an article recently by a woman who got back at her BF that had lied and cheated on her. They were together for 8 years, he cheated on her 6 of them! Ugh. I could only think he must have been an N, based on what she said.

She relayed her story of being vengeful (nothing scary but powerful, nonetheless). She then moved all his stuff out over a weekend when he was away. Changed her phone number, cut off all social media ties, etc. NC all the way.

Most of me disagreed but I could not help but take a certain level of pleasure in seeing this guy get his just desserts.

Working on ourselves is what matters and how we move forward, but how do you all deal with those feelings of really wanting to hurt them back?
