So sorry Ashley and you are dealing with this. It's a fine line to walk in giving out advice to a child without being preachy. It's even harder to sit and watch her make choices that are harmful to her.
You've been given some excellent advice here by Wonka, Wii and Job - I especially like Wii's recommendations.
The scary thing about her taking him back now is that without serious help and intervention, these things can easily escalate and become more violent. You are spot on that he needs to get help for his own good and not just so that Ashley will take him back - that is the wrong focus.
Thoughts and prayers are with you and your family.
