Ready for some forum help

[NewB3]

Still cooking fantastic dinners for the family. Gives me good lunches for the days after. I skip some days and we have leftovers. Wife said she liked the dinners and thanked me over the weekend meals. She Offered to clean the kitchen after meals this weekend. I have stopped picking up her snacks when grocery shopping unless she asks.
Considering telling therapist next week that I just want to work through the issues so we can have an amicable divorce. I really want to reconcile, but do not want the blowback. I got more "I still want to move forward " after the call to get her to be nicer last week.
Our stress comes during the week. Weekends are touch and go, but I can focus on gal with the kids and let her be. I took them most of this weekend giving her time to do what she wanted. She has asked for more time to herself since bd day. That is what she needs among other things. Her stress and depression is so obvious. I am working on being happy, excercising, focusing on helping out more. Not doing it all, but she sees and then she helps out. Recommendations? I have 2 boys at home that know nothing. Wife and I sleep in same bed and try to keep things light, but the elephant in the room..... Lost in 180/don't want her to give up bc I seem to be. I just 180/detaching. I read that another member here had his wife do the same thing. In therapy she said he seem to be pulling away and shutting down so she did the same. How do I avoid that?
