Things seem like they're going ok for you. I wouldn't count the days since you've seen her though.
With validation, for example, her being lonely I would have just said "You did sound lonely so glad you moved in with your brother".
With vulnerability, I was kind of the same. I didn't want to put my problems on my XW as she had enough on her plate. Plus, I got the impression from her that vulnerability would be seen as weakness, with a 'go sort it out yourself then by doing this' type attitude from her.
