Sorry to hear it didn’t work again. It’s a brave decision to look for your own happiness.
I hoppy that you both become happy, and that she finds the will to be happy, because that is quite essential.
I have been in the same state for so long. I wanted to do everything, only become happy or loving myself, no i couldn’t imagine that. That slowly seems to be turning around, which i’m very grateful for, but still, it might me a long way to go. My partner also tried to support me and to help me incredibely much, and now i start to see, that it must have been very frustrating and hopeless for him, that he never could reach me. I think it might have worked contrary, that the more he tried to help me, the more i would resist it. Because, as said before, the wish really has to be within yourself, to change and to be happy.

Out of my own experience, i would like to ask you to be really mindful about yourself, and your own needs. Don’t forget your own boundaries and be clear about them. You seem to be so willing and wanting to help her, please don’t make the mistake of forgetting yourself through that. Because that won’t make none of you happy. And by caring about yourself, you might be giving her the example (even if she is not aware of it at the moment, she might pick it up anyway)
