Is there any idiom or proverb for recommending someone to end their relationship/ friendship/ partnership with somebody whose behaviors or actions seem toxic, harmful, and thus really intolerable?
Like a relationship in which:
- the wife is paranoid and controls her husband continuously and makes the life miserable for him.
- the man is jobless and a drug addict who beats his partner once in a while and asks her to give him money to buy the drugs.
We Iranians use a (figurative) proverb that says:
"(Just) pull out the tooth that aches and throw it away"
It implies that there is no need to tolerate this pain, (if you have tried all the ways for reducing or removing that pain, but they haven't worked,) just get rid of it; even though that "tooth" is part of your body (so you like it and thus it is hard for you to lose it).
We use this proverb when we want to recommend someone to end a painful, harmful, and useless relationship or friendship and not to tolerate it any more. Like :
Why don't you break up with him? He is just a pain on your neck and sooner or later would ruin your life; as the proverb says you'd better just pull out the tooth that aches (= this painful relationship) and throw it away (=end it). There is no use in putting up with this relationship.
I have found "better cut the shoe than pinch the foot" in some "Persian to English" books as the equivalent for this proverb; does it have the same connotation with that Persian proverb?
