Another thing... I do not know what her high hopes and dreams are with regard to the future step father of this baby if she is successful pushing you to leave. It would be one thing if you were engaged in a rare and unusual activity heretofore completely unknown to mankind; then she would be reasonably assured that her next guy would not be engaged in it. But pot use is very common. She may have to sift through quite a few guys to find someone who does not do it at all. And then she may find that people who do not smoke pot do something else that she finds reprehensible. If she is otherwise happy with you, it seems that she would be far better off arriving at some compromise than starting her partner search all anew. Plus, you are the father of this particular baby, which should count in your favor, other things being equal.
