Whatever your decision, I would caution you against asking a man to marry simply because you "want to get married." And as Webdesign said, it may impose undue stress on the man and you may experience him slowly excusing himself away. It would be wise, I think, to discuss marriage in general to get a sense of his thoughts and ideas about it. What does marriage mean to him? What goals does he desire achieving before making that lifetime commitment and so forth? His answers will tell you much about his readiness and save you the embarrassment or hurt of possible rejection. And, remember, dear heart, marriage is not about what YOU want.
Love and hugs, Forever His,
