i think you are failing to see how much you lucked out.

you dont want to see her, she doesnt want to see you,

if this stuff is actually somethings that you need to have, how can pass up the opportunity to go, grab it and get out.

but, it reads to me like you want to have some final impact, go out with a bang or something ... letters to the parents, final farewells, collecting memories ... let me ask you, if your wife had done all of that would you be feeling the same impact as you are now?
