Gb I am there with you. I find it so hard to wrap my head around the fact that h thinks it is so easy to move on.
My h and OW used the same words. I broke him. She is going to fix him. She saved him. Notice how there is no action on h's part. He is a non-participant in his life.
I know from experience that the allure of being a savior can be powetful. I met h a year after his divorce from w1. I believed what he said about her. She never believed in him. She beat him down. Blah blah blah. At the time I didn't know anything about codependent relationship.
I find it odd that OW kicked her h out many years ago for his drinking and now is with h and believes him when he says he only drinks because of me and will stop for her. Clearly she is just as deluded as him. And she admits that h is in mlc. What does she think that makes her.
In your case I don't know if gf is deluded/blinded... she is just not developed yet. She doesn't have enough life experience to really see what is in front of her.
Your attitude and positive thinking will help you and the kids come out the other side of this ok.
Wonka it was helpful to read your perspective . It sheds light on some very confusing things.
