I would continue as you have been doing. Try being a friend, a good listener and not put pressure on her. She is sitting on the fence and until she decides what she wants to do, she will be there. The less pressure you put on her, the better.

I wouldn't rush MC. If you think you need to see a counselor, by all means do so. However, if you push her to see a MC, she will take what the counselor has to say and only hear what she wants to hear and then she will probably say "see, it's not going to work for us".

For now, continue as you have been. The less stress you put on her, the better.

Sit quietly, the answers will reveal themselves when you least expect them to.
The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
