I am pretty sure she is having an MLC. What now?

I think I am starting to get a grip on what I need to do.
I beleive it is important for me to be her friend right now, as when we separated I lost more than a wife. We had a pretty good (not perfect) relationship. We did things together and enjoyed each other's presence.
We made a family together. We took interest in each other's hobbies.
I even expected her to have some sort of crisis after her dad passed. I told myself five years ago "I wouldn't be surprised if she had an affair or something" but I thought that passed. The losing weight, piercings, motorcycles, bizarre (childish) behavior were all things I understood and though would pass. I may not have taken them seriously enough...but I know it is not my place or job to diagnose or push her to get help. If I mentioned it I know she would have gotten mad at me.
She is in counseling now and I hope she finds what she is looking for.
I am working on my relationship with the kids and living on my own. I don't think I would be able to constructively work on a relationship with her in her current state.
I plan to live my own life and see what happens.
I continue to read and get counseling to learn my mistakes for the next relationship...understand my panic and my reactions when my lizard brain is active.
