Yeah, there's life after D. With time and space, you'll be at a better place emotionally.
As for your D14, I would be involved in her life regardless of her choice to live with her Mom. I'd make weekend plans with her and your D20 so you all can hang out together. These young girls need a strong male presence in their lives. They may scoff at this given their young ages, but really deep down they NEED you.
Sure, D14 will protest but just tell her that she's coming with you whether she likes it or not. Be persistent and not give up.
