Congrats Lance! That's wonderful! I wish you and your wife-to-be nothing but the best.
I haven't been married (yet), but my parents have been married for over 30 years, I've been with my boyfriend for four years, and we live together, so I can offer some advice that I know.
Know that you're not only marrying the person you love, but a person who is also your friend. A good relationship is a friendship just as much as it is a romantic relationship. Maybe that sounds like "duh" advice, but I know too many people who married and realized that they never really were
friends with their spouses. They didn't want to spend time with them, didn't want to confide in them, didn't enjoy doing things with them. And that is so important. Don't only be a good husband--be a good friend.
Realize that you will fight, and sometimes those fights will be big. It's inevitable, and it says nothing other than you and your wife are human beings who sometimes have disagreements--like every couple. I know people who fight with their spouse for the first time after the wedding and then freak out, thinking that it means the end of their marriage.
Apologize if you're in the wrong, and apologize as soon as you can.
A strong relationship is built on honesty, and I
cannot stress that enough. Be honest with each other and don't keep secrets.
I'm really happy for you!
