only ever. get rid of the ones that pull you down. the key words - pull you down - they're behind or below you, you're not going that way. they can stay there. you've got things to do and a mind and wellbeing to be and do more. there's no time for settling to make the "pull you downers" feel comfortable. they're not you're people either.
Avoid people who mess with your head. Avoid people who intentionally and repeatedly do and say things that they know upset you. Avoid people who expect you to prioritize them but refuse to prioritize you. Avoid people who can't and won't apologize sincerely. Avoid Avoid.
