Peggiann,
It is so difficult to come out to those who are near and dear to us. We agonised over this for quite a while ourselves. My wife's mother is 85 years old and not in the greatest of health either. At first we thought as you do that we would wait to come out to family until after she passed. However it comes down to this... we love and respect her as she does us, so it is only fair that she know. Once we decided on that it happened in very short order.
Firstly we told the brothers and then we told her this way she had the brothers to talk to about it. It worked out really well, and although she didn't understand it, and she thought that I was just looking for attention, she still loves us and still visits and phones. Nothing seems to have changed, she calls me Steph or Stephanie and I think that we are closer now than we have ever been. She deserves our respect, our honestly and our love, and to hide the truth from her would have been quite frankly very wrong on our part.
It's a very hard step to take I know. Sometimes the fear of rejection, the look of disappointment, the fear of disapproval, and being cut off is overwhelming. BUT, having come out to her has been so freeing, so much of a relief that we don't have to worry or hide from her or the truth anymore.
Give it a lot of thought, before it's too late.
Steph
P.S.
I'll send you a copy of the letter to my mom. She lives in England and I didn't want to do it over the phone. Her reply is posted here on Susan's.
