What makes you think you have super mind powers to break through to her?
Focus on yourself and kids buddy. Do what make you and kids happy. She is wayward and you need to treat her a such ~like an addict. You cannot break through, only she can find herself and even then she might decide not to be with you.
Its hard, it took me months even after physical separating to stop thinking like a lovesick husband. Some dudes/dudettes on this board has hanged on longer.
Read Sandhi's rules. Make a Plan, create your boundary, be the best you [B] for you and your kids[B] not for her. Everything you do will feel counter-intuitive. Thats normal.
