Yo Unsure77. I'll put up options as I see them if you like, feel free to ignore or even report my post, or feedback 2 me.
u have letter. dont want her children to see.
do want her to know things could be different if she believes.
u left for safety, r miserable and lost now.
That's some courageous stuff to confront... options...
1. give her the letter without any conditions. she could show her kids or not as she chooses.
2. write at the top of the letter "private and confidential for HER eyes only"
3. edit the current letter, so that it shows only what u are comfortable the kids also seeing.
4. keep being safe. so if you hand the letter over personally u need an ally there.
5. could post the letter OR, have the letter couriered to HER and only acceptable by her, needing her signature on it. Couriers do that kind of stuff all the time fyi.
6. what things/stuff outside of HER, used to inspire you, or used to make you happy or content?
7. options I/we haven't thought of yet.
