One man wasn't enough, she had to have two. Now she has none. Hmmm, maybe that's why everyone else is satisfied with just one!
Show her that she has none. Do not bail her out of her mess. She made it. It is entirely of her doing. I think moving out is a very good plan. It is her father's house. Let her family take care of her. But make sure they know the truth. Because that is most certainly not the story she will tell them. She will paint you as the bad guy who abandonned her. Deal with her father. Not her. She needs counseling. She will never make a good mother to a child unless she gets help.
