While I agree with you that marriage is about compromise, having a child when one person doesn't want to is not a compromise. Compromise means win-win. I think counselling is a great idea, because having a mediator can help the conversation stay on track and be rational. For what it's worth, I think it sounds like the ball is in both of your courts to think things over. I wish you well, and I hope everything works out for you.
ETA: in case you think I'm just being a negative nancy, I should add that I had a baby after an unplanned pregnancy when my husband didn't want me to. Yes, DH adores his son, but the damage to our marriage is irreparable. So, my life experience is probably colouring my answer somewhat.
