Take it from someone that has been married for more than 25 years, it's the best choice you can make. Having someone there 24/7 to discuss your concerns, your pleasures, and your future.
Just remember one thing, don't go to bed mad. It sounds so simple, but it's the key to a healthy marriage.
Enjoy this time, because the closer to the wedding, the more stressful it will become. Just tell your guy to agree to everything, just nod yes with every choice. That's the key to a successful engagement.
Very happy for both of you.
