I am sorry that you both are in this position, even if your bf doesn't know he's yet! Honestly, my feeling is that if he won't marry you within the foreseeable future, I doubt that he'll be willing to make all the sacrifices that come with being a Dad. He may completely change his priorities once he knows that you are pregnant....you just never know how a man will react. Ask yourself this: If he's unwilling to commit(really commit, now-not in 3 years!) when you weren't pregnant, would you be comfortable staying if he wants you just b/c you are pregnant? Things change, the 'new' wears off the idea, and the weight of responsibility of a baby sets in, and some men(and women) cannot handle it. Good luck to you all, in whatever is decided.
