I Refuse to Forgive My Wife for What She Did to My Son

I was horrified. When I confronted her, she claimed she was just “helping him grow up” and that I was being emotionally manipulated. She ended up leaving to stay at her sister’s until I “stopped coddling him.” But after hearing her tell my son his grief is a burden and insulting his late mother, I don’t think I want her to come back. My son needs a father, not a stepmother who views his trauma as a competition.
