I'm sorry I'm late with this but I want to thank everyone who replied. The anniversary date wasn't nearly as bad as I'd feared. I spent the majority of it alone, which was what I wanted. After mass, I went for a long drive, 6 hours round trip, which is something we would have done together.
So, now I've weathered the major hurdles, holidays, anniversaries, birthdays, wedding of one of our sons and the birth of our first grandchild. I've found that none of them were as difficult as I thought they would be. The hardest times are the unexpected ones. The ones where, out of the blue for no conceivable reason, missing him is just overwhelming. Thankfully, those are getting fewer and further apart.
I will always miss him, but it's getting easier and I think I'm ready to move on. I'm not looking to replace him. As a matter of fact, my "ideal" is different from him in many ways. That doesn't mean I didn't love him and won't always love him. As a matter of fact, I think it honors him in a way.
Anyway, thank you to eveyone.
I am very happy to hear from you and to know that the day went better than you expected. God bless you.
