But you don't have to trust her. Only you can decide if she is trustworthy to you or not and take your actions based on that. If you feel that you cannot trust her then that's the way things are - you don't have to (and you probably even can't) force yourself into trusting her if you really cannot do it.

On the other hand, she has her own life and has right to make decisions about her life according to her best judgement. She has decided to move permanently and if that decision feels right to her then there's nothing you can do about it. Of course you can be disappointed and rant about it to her and to PC but that does not mean that she as to change her life decisions because of that.

I'm absolutely not judging you because I think I can understand how it feels violent and disappointing to you. But I wanted to say that your posts come off as if you really think that she has any obligations to coordinate her life with you, give you thorough explanations about her decisions etc. It feels that you truly want to control her and then are angry that she does not submit. It feels like you really believe that she should submit.
