Mikey,
My brother got divorced 5 years ago. His baby boy was 2 years old.
His wife started running around when the baby was 3 months old. She wouldn't come home for days at a time. By the time their son was 1, she was pregnant with another man's child. She still lived with my brother. Would come home at 3am and kick him out of the bed so she could have it. But most of that 9 months she wasn't even home.
Yet he clung, ever so tightly, to that dream of the "perfect family". A mom and dad in one house, living together, raising their son. That image is what he couldn't let go of. And so he put up with it for 14 months before he realized that what he wanted so bad was already gone and he had to make a new reality for himself and his son. Once he accepted that, and took that scarey first step, the rest came along relatively painlessly. But for the longest time, he just couldn't see.
I'm not sure why I'm typing this other than it felt relevant for some reason. Sorry if its not. The happy family portrait in your house doesn't seem to include McWeedy right now, at his own choosing. I pray that changes.
Anyway. Kudos to you for respecting yourself, Mikey. And since wife is still around at this point, I guess I'm inclined to think maybe she'll follow suit. And that first step is always the hardest, but have faith. Things will work out in the end.
They always say what doesn't kill us makes us stronger. Well, welcome to the Hall of Justice, Superman.
Hugs.
