Dearest Casbow,
Your post touched me so much because I have a similar situation although it is with my youngest son not a sibling. In the darkest days when my husband was at home and before he was sectioned I had a phone call from my son who was 44 at the time(from my first marriage) he was crying that he and his partner were splitting up and would I lend him money for the deposit on a flat and he would pay it back when the house sold. I took him at his word and lent him the money, he knew my husband was ill but he didn't hesitate to add to my distress.
When the house was sold he wouldn't keep his promise of repaying the money, instead I just got emails telling me what a useless mother I was and that he wasn't going to pay the money back.
When all of this was going on my husband had just gone into care and I was experiencing the most unimaginable grief, so instead of some support or kindness all I got was lies and insults.
Eventually when I got my emotions under control and my head back together I took the emails to a solicitor and changed my will, leaving him nothing. Do I regret doing this - no. For you own child to behave like this is unforgivable. I have never replied to him and recently he has started sending cards at birthdays, mother's day and Christmas but they just go in the bin, I never reply.
Like you Casbow, I don't want other people in my life and for the last three years I go daily to see my husband and at the staff at the home have become part of my life and are more real to me than family. What really hurts, and I see it in the posts here is how there is so little understanding of what we go through from the people who should care the most. I know some people will think that I heartless or cold but I am not I am crushed with the whole awfulness of caring and the way life has turned out. We put on our brave faces and carry on because there is nothing else we can do, so if people, especially families, cannot see that then thank god for friends who do understand.
Take care Casbow and at least on TP we do have friends who understand.
Love to you Kathyx
