Wife just told me doesn't want to be married

@in shock thank you for the list, very informative and helpful. I will be printing it out.
Thank you everyone that answers, its good to know you are never truly alone.
I speak with friends that know both of us regarding this just to get perspective.
I am not texting or emailing her unless she reaches out to me first.
We talk about the kids, finances and scheduling thats pretty much it.
Its also hard right now cause my sons bday is next week and we are figuring out what to get him plus holidays coming up and how they will work.
My goal is little contact as possible.
I pick up my kids on tuesday and thursday she works late so I get to see them eat dinner and put them to bed. She comes home from the gym 930pm. We say hi give an update on kids and I am out. Thats it.
I had my kids this past weekend and when I dropped them off she started the conversation asking about my sisters bday. Which was a fiasco cause my sister is all stressed out and so is my family. So I gave her a quick update that was it.
When I am there I only do the dishes that I use with the kids and get the kids lunches started up for the next day.
She just asked me to do that within the last few weeks. I think after her own therapy.
Should I offer to assist in hanging things or picking things up? For instance she just bought a mirror to hang and its a two person job. I don't want her to ask a certain person for help. Do I offer?
