Do you not care about your child/children? Listen, life it tough, deal with it and not using violence.
Makes me sad that you are ok with disfiguring your "loving wife"! That's how this tread was titled. Do you remember anything good about the marriage, because if you don't, you need to let her go. If all you really want is to "get even" with her and THEM, please try to get some professional help with this.
