Maintain regular communications with the person in prison. Remember you are the chief source of contact with the real world. Prison is filled with false information and is an abnormal environment. Encourage reading and watching news, public affairs and educational television. Don't let them throw you.
Prison sometimes brings on such reactions.
Children must not be ignored as the loved one will be missed as much by them, if not more. Don't feel guilty about telling the offender of your need to control expenses through limited visits and limited phone calls. Write letters instead. Try to stay in communication as you work through the problems. You need one another in this difficult time.
