That’s the hard part when you love somebody so much. We lost our first child; since then 2 of my sisters have lost their husbands. It’s painful to even remember the joyful times at first, but after a while the joy comes back. I tell my kids that Heaven is where you never have to say “good-bye” ever again, though for a while here you have to be in a separate room from the one you love. It sounds so flippant, but it helps me when I remember that.
I can not even image.
The one blessing, is that I know mom and dad are there to greet Frankie.
I believe you are correct,at least through my own experiences that joy will return mingled with a longing that I can not explain, I just feel it in my heart.
