Considering Dating a pregnant girl, please help?

Might you consider marrying the girl. She needs support and a father for her unborn child. If you know you don;t want that then don;t raise her expectations only to dash them later - or at least be very clear about the circumstances involved in your dating. Also be aware that the biological father may change his mind and want access to his kid who may end up calling you Daddy. What if she decides she should be with him as he is the child's biological father, but you had already fallen in love with her and her kid? How would that make you feel, could you cope with it? Basically try and imagine yourself in a situation in the future where you are together long term and decide if you could handle all the tough situations that may arise. Basically go into this relationship with your eyes open.
