^^ I'll throw my thoughts in and say I agree with all the other posters also.
People aren't looking for the gory details of what happened they're trying to understand why it happened to help you. To help you.....
It's your life and you can ignore this but if you really want to make changes that will last you're going to need to dig deeper to understand why you acted the way you did.
Listen, you may have come here for the quick and easy way to save your M but you now have the oppertunity to really change you. That may work out being a new M with your W in the future but at the very least it will give you the tools to be able to succeed in your next relationship if it's not her.
Accept what is, let go of what was, and have faith in what will be
