Excellent! Just remember it's "for better or for worse" and indeed there will be the bad times, but they make the good times just that much better. It's work and the relationship changes/matures in different ways over a period of time...but I'm here to say -at least in my case- My wife of "soon to be 25 years" is certainly a very special lady, and I have to keep her!! I'm a dog and she puts up with me, takes care of my two teenage sons as well as me...she holds the family together and we let her know it!
Sounds like you've really planned a moment to remember!!
