<human>: Can you give me the gist of the text in a nutshell?

I'm being really blunt in the title. I have just run out of patience. I want to understand, I want to be helpful, but I just cannot do this anymore.

My parents, aunts, uncles, grandparents and family friends have tried to warn her. She's pushed them away, and now it's just me and a few friends she bothers talking to.

I just don't have it in me to keep in contact with her. Every time she talks, I have to bite my tongue. It's the constant excuses she gives about her bruises, and how she sidesteps any mention of her terrible physical state. I want to shake her and tell her everyone knows her boyfriend's cheating on her and beating her, but if I do she'll just block me like she did with the rest of our family. But I'm going crazy being the only link to our family.

And you know what? I can't be the messenger anymore. I'm throwing in the towel. I'm mentally and emotionally exhausted.

I've heard you have to let someone fall very, very low before they'll leave the abuser. Is this true?

Any advice, or similar experiences from abuse victims/family members?
<bot>: Cousin's in an abusive relationship. I have lost sleep, and I have lost hope. I don't want to keep in touch with her anymore. Too cruel?
