getting married because she's pregnant?

This is based on what is best for the child. Problem is, people tend to get so wrapped around themselves or the relationship because they're not yet fully mature or prepared. If you and your partner can make the relationship work out and keep it without resentments, yes, you should get married. I've seen it happen, it has worked out for the best for other families. If it will just hurt you, your partner, or your baby then don't- you must consider the effect of your relationship will have on the child.

Do you think it's a good idea to get married simply because you're pregnant?
