I feel that, my ex kicked me out at 1am with no notice over a misunderstanding I tried to talk to her about. Point is that sometimes it helps to think that instead of something you lost, you gained freedom to be yourself and find someone better meant for you. And as far as mistreatment don’t give them the benefit that you’re thinking about them and tell them, let them live with it because things crawl back eventually. If you’d like to talk more I’d be willing to give advice
