This might scare some of you on this board, but my husband and I actually do pre-marital counseling. We always tell our couples that the first few days (even the first few months) are almost always a let down. (Sometimes we even go to the extreme of saying "your honeymoon will suck" but at least then almost anything good will beat their expectations
) Now, that doesn't mean the marriage will be a let down, it just means that human nature puts a little too much emphasis on one day and the relationship is meant to grow over a lifetime. So, anyway, your feelings are very common even for people who spent a lot on their weddings. However, unlike many others, a few months from now you won't be fighting about the bills. Congratulations!
