That is something that makes love from others feel so fragile to me.
There's a certain point of suffering where the people who love you either don't anymore or have to leave you to not get dragged down themselves. And it can happen so fast.
I don't think anybody would say that to a person they love, but it is healthy to do so I think? And can you really blame somebody not wanting to stay with a cockroach (metaphorically speaking)?
