MLC World, Your sitch and mine sound about the same except my W anger at me is always there. She blames me for how she feels and uses that anger to move ahead in her journey.
My W has basically abandoned 2 of the 3 kids which is what you were asking. They see her once in a while but she seems OK with it that way. The ironic thing is she tells people she is a great mother and is really close to the 2 oldest. How you can see your oledest once every two weeks and be close i don't know.
My wifes denial started in June 2009 with the bomb in March 2010 and continues in the tunnel today full blown. i have been able to detach and do a good good job at GAL'ing. I really don't see my wife coming out of this fog but I have given her the benefit and can empathise somewhat with the sitch.
Hang in ther MLC world. We will all benefit from this whether we salvage our Marraige or not. Keep being there for your kids. Thats my main focus as well.
