Physical & Emotional Abuse Support Group
Abuse is a general term for the treatment of someone that causes some kind of harm (to the abused person, to the abusers themselves, or to someone else) that is unlawful or wrongful. No one deserves abuse, period. Abuse can be emotional, physical, or sexual.
In some states, your spouse can ask for counseling and a chance for reconciliation when she answers your divorce papers. A judge may or may not grant her this request. If he does, it will slow down your divorce process while you attend counseling. It wont stop you from getting your divorce, however, if you tell the court after counseling that you still believe the marriage isn't savable.
What stands out to me about his comment is that he has CLEARLY gotten legal advice ... maybe from a friend but maybe from a lawyer.
Don't let him take control of this. Don't let him take control of your kids.
And be prepared for him to use the kids as weapons - he has already said he intends to do so. Document these threats and anything else he says about how he plans to use the kids against you. Don't tell him how wrong you think that is, or he may stop telling you (he'll still do it tho).
