Marriage is not all about getting the costliest engagement and wedding rings and an expensive wedding gown. There is more to marriage than the ring and dress.
You should know that you are going to be living with someone you've not been living with from birth. You both share a lot of differences, and those differences can make marriage interesting.
As you live together as husband and wife, you need to learn from and about each other that is why marriage is called a covenant relationship. You are in it to learn and to teach each other.
