I did and wish I hadn't but W always knew I wanted to return so when I thought I was ready I did just that. My W wasn't happy about it and did everything she could to try and get me to not move back but I told her it was part of me moving on. She said I was forcing her out I told it is just as much her house as mine and she could stay I had no problem with it. If she wanted to leave I told her I would not stop her. Lo and behold it has been 3 months and she is still here. Not the best situation but better than when I first returned.
If your W wants to see what it is like to be on her own she can move out and see it from that side instead of you leaving. I suspect she told you this to see if you would actually consider it.
On the doing things for each other, I not sure how to answer. My W and I do our own laundry, dishes, etc. but it has been this way for long before we S.
When I do things around the house like shovel the driveway sometimes I get a Thank You sometimes I don't One thing I never do is ask my W to do something for me.
If the dishes are your kids I see no reason why you don't do them maybe leave her wine glass for her to clean. Seeing as she is cooking for you and doing laundry maybe it would be ok to do the wine glass also.
When she does these things for you do you show genuine appreciation?
It seems like maybe these things that are your routine things can continue just don't expect it to continue because it might not, if it does I consider it a bonus just don't ask for anything "extra" or do too many "extra" nice things for her as she could see this as pressure/pursuit.
As far as her getting ready in the morning for work and not having time for the kids that sorta bothers me but I don't have an answer for you on this.
You can live there and not be there for your wife by GAL and doing some 180's and working on yourself for YOURSELF.
As long as it doesn't adversely affect your kids, do as much stuff for you as you can, don't worry about what your W will think. If you do this I suspect your W will take notice. Actions speak louder than words, if she mentions she sees some changes in you thank her and say "yes these are things I am doing for myself" never ask her if she sees changes that will make her think these changes aren't permanent.
keep a PMA!!
