Knew this nuke was coming eventually.
The blast was over and done with as soon as the wife was even mentioned.
Grieving? No.
More like free from the shackles of un-reciprocated love... in the form of depression.
The recoil will eventually end as all predicted cliches are.
Though, I suspect it's going to be a few chapters to get it over with.
TL;DR Chop-chop, get over it.
