Hearthope, I don't know exactly how you feel, but I have had to mourn the loss of a grandchild, too. My difficult child chose to have an abortion 3 years ago. I was very much against it, even though the father was a difficult child heroin-addict. husband signed the papers and accompanied her to the abortion clinic. I wanted no part in it, felt like it was murdering an innocent baby. My husband and I separated not too long after that.
I have forgiven them both (I've also asked difficult child to forgive me...I do respect that it was her choice, not mine, on whether or not to have a baby). husband and I have reconciled. But still, tears run down my face as I write this. I will always feel the loss of that grandbaby.
