Why would one cheat

There will never be a valid reason,
I said,
As I bask in the attention of the person i'm not involved with.
Maybe that is it-
To chase ways to cover up the missing elements
It's never a valid reason.
Especially if you haven't even gone through the issues with your loved one.
If they still fail and you really want the littlest things they can't give;
Leave. Leave and not cheat.
It hurts but it's your fault nonetheless,
And it hurts but at least one of you will get out less scathed.
