I know it, DH knows it so why can't I stop crying?
because you love her! I went through something very similar about a year ago--and most of the people posting here have clearly been through some version of this, too--and it is really heart-wrenching every single time. I find it interesting that we are given constant opportunities to love beautiful beings we know from the beginning most likely won't outlive us. But we love them, anyway. And we do it again and again, and accept that our hearts will break.

My thoughts and prayers for you, Maggie, and your DH.
