I too am doing more around the house. I suppose if I am honest initially thus was mainly to help W or be nice. Part of it was to just be more involved.I know now that this has not and will not endear me to W. Now I continue and am even more proactive at just doing what needs to be done. I am now much better at seeing ahead what needs doing. I am doing a fair share of household stuff but not the lion's share.
For me doing this is something I want to bring to a future R. Before I waited to be asked or I asked about doing such stuff. I am careful not to be bending over backwards to please W or save her from doing stuff. What I am trying to say I am trying to get the balance right and to be roughly where it would be if everything was OK in the M.
But NOW I am thinking less of impact on W, although still consider all my actions so as not to counter my overall goals. Now I am omore consciousof the possibility that someday I will have to do everything on my own. I never feared that but I don't want to just be able to manage, I want to be best I can be so it won't be a stress. I want to be ready so most of my energy can be used for me and esp for my boys.
You are heading towards that, and whether you want it or not, it is likely you will have to run a household alone. Be ready. You need to use the time you have left before selling to be ready. Maybe W will notice that and rethink things but you cannot bank on it.
I know I probably did not reply to your biggest issues but I'll leave that to those already advising you so well.
