yes...
you file the disappointment away

it is harsh and cruel but he has chosen to be with someone else

he doesn't like being at home because he doesn't feel like it is his home anymore

he has made his life elsewhere

it is draining to make small talk with someone who is desperate and wants more

his neck is not aching from guilt
and if it is it doesn't matter to you

he is gone
let him go
stop trying to force him into a mold you have created


work on you
work on making you whole and happy WITHOUT HIM

if he comes back then...great
if he doesn't...great
