red_evil I am sorry to say that you may have to chalk this one up to experience. Although it must hurt you so much that he has left you in such a predicament and from what you say he is in search of his next victim right now. But any attempt to make him responsible for his offspring, or to try and hurt him out of anger, is going to cause you big problems that quite simply will not be worth it. This is easy for me to say, but difficult for you to do, but believe me when I say the best thing you can do is "Walk away..."
