I don't want to be hard on you because you seem awfully sweet, and so sincere in your need for advice. But I often ask people in your position, "What advice would you give someone who had the same dilemma?"  I think you'd say, you can't have a solid future with a guy who wouldn't recognize the truth if it bit him in the butt.  A statement about having a child with another woman (if it really is true he doesn't -- and who would know with this guy), is so absurd, it makes no sense. There's nothing cool in saying that, and if he thinks it is, he's deluded and ill-informed. Oh, I suppose maybe he thinks he's a stud by saying that -- he can knock up a girl and, then, bring his off-spring a gift as a token gesture to acknowledging his child. But wait, that even sounds ridiculous!  I think you have no faith in yourself that you can do better than this odd duck, but I have a feeling I can't convince you that you are better than this farce of a relationship. Your self-esteem may be too low to bring you into that reality. But I advise you not  to go ahead with this relationship because a liar seldom changes -- he only gets better at his lies as he ages because it is the only thing this type of person knows how to do. There's some psychological component to it, and it will only drive you crazy if you accept it hoping it will change someday. Lying is a form of manipulation. It forces the individual who is being lied to, to make judgments based on that lie. It's a sad statement about him yet, ultimately, a sadder statement about those who put up with it. My advice is to leave him, and get your life in order. Find a guy who respects you, and whom you can trust. I don't know why you don't think you can have children -- but I wouldn't even consider it with this guy if you can. That would keep you locked into having some kind of relationship with him for a long time to come, and that could put a crimp any future plans without him.
