Just my opinion...
Sometimes the best thing you can do is to let them know "I'm here for you when you need me," and leave it up to them.
I know that sounds awful, but really try to resist the urge to jump in and "fix" things.
Obviously, you know your family better than I do, but sometimes people have a need to work things out on their own.
Right after my wife and I got married, we had a string of serious setbacks. (For one, just 13 days after our wedding I had a knee injury that put me in a wheelchair for four months.) We never sought help from anybody; it was tough, but we worked it out just fine. We grew stronger because of it, but we're both fierce individualists.
Life is tough. Be available for them, and let them ask.
I would love to hear from others on this.
And pray for them and for yourself - for God's healing, grace, peace, and love.
May these all be yours, too, Scott!
