I need to say this. I’m feeling a little of animosity in some replies towards how the OP proceeded in relation to her son. Correct me of I’m wrong.

She stated that she needed support and not being criticised for the decision she had to take. It’s not easy to stand up at your boundaries with a son or a daughter but there are moments that you as a mother, a father have to make painful decisions for their own principles. Principles are part of what we are. And also there’s another strong motive that is to avoid a bigger damage for all.
Again I don’t know the details but we need to consider both parties.
