STFU. Take care of yourself. give her to God, you can't do anything for her.

In the grand scheme of things IT REALLY DOES NOT MATTER... Sadly...

So you are/were right. So what? You are the moral victor. So what? So she's a cheating slut. So what?

See where I'm going? IT DOES NOT MATTER. Not one damn iota.

It is still early days for you. STFU.

Stay strong buddy...

You have to heal, and heal a lot. And detach, detach a lot.
