Frustrated and Saddened

[Iamworththetime]

The last thing I want to do is bring up the separation

I wouldn't bring it up at all, if she wants to go, she'll go, no need providing the push.

Also, do you guys have any suggestions as to how much involvement her family should have in this situation?

I personally don't think they should have any involvement, but you can't control what she tells them, you just shouldn't provide anything unless you're sure that THEY want to help both of you and not just her. My inlaws don't know a thing as far as I know.
