How can I support someone getting a divorce and becoming a single mum?

The basics:

• Three young kids
• She’s the breadwinner and has done everything for this family since day dot
• Non US
• Renting a house

I’m very, very close to her and very, very proud of this choice. She’s the type to deny help, but I want to make this easier for her if I can.

What would help? I’ve offered all the usual – mental/emotional help, to take the kids, meals – but she won’t take it.

Any advice? Should I back off or any suggestions on what would be appreciated?

Any books or hobbies or recommendations for her separate to the kids and as an individual?
