Yep. "Next Girl" #5 here. It took a bit longer for me to come around than the other ones (I was stubborn and thought I could "save" him), but yeah, my marriage/relationship with my XAH was the same as the previous relationships he had. He meets a girl, charmes her, they have some happy moments, things turn ugly as he is abusive and an alkie/drug user, they have a child which effectively ties her to him, the relatioship deteriorates and he begins to make threats to take the child, he runs off after losing custody...Lather, rinse, repeat.
My DD is his fourth child, and I assume there is a fifth or sixth already.
Now that I'm gently poking my toe into the dating scene, I always examine the way a man discusses his ex, and what sorts of relationships he has with the women in his life, be they friends or family. Those are telling clues...
