How do I help my friend leave him for good.

[bumblebee345]

My friend had been with her boyfriend for 11 years. They got together very young and are still immature now at 29. She cheated on him then he had an affair which I think is still going on. They fight constantly she ends up driving off and coming to stay with me. But she keeps going bk. part of me thinks it's purely because she knows if she walks away he will move on quickly. She knows deep down he doesn't want to be with her. She blames it all on him but she forgets she cheated first and broke the relationship.

I've never known a miserable relationship like this. They have been arguing for a year non stop. Keeps threatening to leave him but never does.

How can I help her see sense

You can't help her, and you shouldn't enable her. Next time she wants to stay at yours because she refuses to deal with things like an adult, tell her no. She has no hope of growing up if everyone around her keeps picking up the pieces.

You can't.
But tell her you're fed up with being involved in her ridiculous situation, to stop moaning to you about it and to stop coming to stay at yours when she storms off.

@Aquamarine1029 has nailed it. Your friend has no incentive to make the necessary changes if everyone else supports her in her dysfunction.

I know your right. I'm 3 years older than her I find it very hard as it's utter madness storming out and leaving but then constantly going back to him. He's told her he's miserable and not happy she won't have it. I'm not sure if he's asking her to come bk. but this has been going on for a year. She cheated on him 3 years ago.
