why you should never try to figure out what your ex is doing

Best to let an ex be an ex, with a question mark
left at the end of his story,
and write down that he has gone on to live
an ordinary life and do ordinary things.
Tell yourself he is up to the same things,
night after night,
day after day,
just playing video games or drinking,
and forget the fact that he's in love
and he loves what he does
and was another version of your better self,
taken from you without your consent.
How did you manage to think alike, yet come
to such different conclusions?
Best to forget him and get on with your days,
and fill them with cannoli cream,
and sprinkles, and chocolate chips,
because if you figure out he is happy,
and that you didn't matter,
and that he is in love,
and you aren't,
and that he didn't care about you,
and you cared about him,
and that he became everything you hoped to be with him,
while you remained mired, angry, frustrated...
I can assure you it isn't going to be a good day.
So don't even bother to look any which way but forward.
