Hi @Owlette, first off, congratulations on your engagement
One piece of advice I can offer you is this, Campus Crusade for Christ, now called Cru, has a great program called, A Weekend to Remember, for both married and engaged couples. My wife and I attended both as an engaged couple and again as a married couple a couple of years later.
You can read all about it at the links below. Just FYI, my wife and I will be happily married for 31 years this August, due in part to the things we learned about marriage (and still use today) at A Weekend To Remember
--David
p.s. - while you will learn many important things there about being and staying married, the other reason that it is truly "a weekend to remember" is because of how much FUN you two will have
hi the key to being happy in marriage is to bring the love joy and peace you have with the LORD into the marriage and encourage one another in journey through this life. Men and women are different with different needs. A book called love and respect is good as it is scripturally based and examines our differences. if you are planning on kids another book called parenting by the book is one you should read together as it shows Gods ways of parenting by the Bible are much different than the way our culture does it.
But I would strongly suggest a round of INVASIVE premarital counseling to help lessen or avoid the future problems. It must do an in-depth examination of finances (#1 cause of divorce) Sexual attitudes and histories (#2 cause of divorce) doctrinal differences, child discipline, and a host of other things.
By biggest advice is to enjoy being engaged, it goes by really fast and you never get it back. Also, accept there will be at least one major disaster at your wedding and choose now to laugh at it.
