So my friend here on the base is getting divorced and it's really sad.

She and her husband have been married for 13 years and they have 5 children and he's leaving her for another woman. She's been crying every day for the past week and I just don't know what to say to her. I've been bringing her cookies and stuff and inviting her over to my house, but nothing seems to lessen her pain. What's really strange is they seemed so happy together, but now she's been telling me all of this bad stuff that was happening in their marraige that I never would've guessed. Worse yet all of her other "friends" are shunning her as if her divorce is contagious or something.
So does anyone here have experience with this sort of thing? Is there anything I should do/shouldn't do for her?
