Djatamps,

I'm so sorry to hear about your relationship breakdown with your mother. That must have felt awful for you to read her reply to your letter. I can fully understand your not wanting your children to be dragged into this pain. I'm sorry that you've had to go through that for 49 years.
You've found a great place for support. The members here have had similar experiences and understand. The site also has tons of tools and resources that can make things better for you and your children. There is hope—you are not alone.
How are your children coping with this development? Do they know about your intentions/the letter?
What kind of support system do you have around you?
Keep writing, it really helps. We're here to support you.
