Don'y beat yourself up, Nate. Most of us "did all the wrong things."

You're on the right track, though.
Set some goals for yourself.

What are some things you want to do for you?

What are some things you've always wanted to do but felt like you were held back from doing?

Go do those things now. There's nothing holding you back from that.

Goals are for you, BTW. Don't center your goals around your interactions with WW. I made that mistake in the beginning, too!

Remember that she is the one who is leaving you. She is the one cheating, and you don't deserve that, no one does... Let that give you strength.

You are a good person and a great dad. She should be lucky to have you and she needs to feel that loss. She'll feel it when you GAL for yourself and start doing things for you.

How would you treat an employer who fired you? would you try to get them to talk to you? would you center your life around trying to get that job back? That's your M right now. your WW went out and found a replacement for you before you even got fired! it's an unbelievably 'effed up situation. The same situation I was in and many, many others here are in.

I know I'm coming off as harsh, man, but I need you to understand that your worth to your WW is nonexistent right now... the key there is "right now."

You need to find that worth within yourself. Find the man you've always wanted to be and she will see it, but make the changes for you, or they will never stick!

there is a guy named "job" and he posed a wonderful thread on how to detach over in the MLC section (I think, if it's not there, I'll tell you where you can find it)

That's your homework today, man. Read that thread and start applying that to your sitch. You'll get there; detaching takes time and knowledge.
