Need Personal Letter Written

I am looking for someone to complete a final draft letter to my husband from notes I have been compiling for two years.
This is a personal letter asking for a divorce. He is a covert narcissist so choice of words is crucial, stating facts and discussing feelings is important, will being kind.
This is a kind letter. I am heartbroken to make this decision but need him to understand (he won’t because he’s a narcissist) but for court and future purposes would like a well written letter.

I have sections of the letter I’ve been compiling and will send you all of that to make your own.

Working with with possibly a counselor / therapist background would be ideal!
