I would recommend not contacting him and letting him know how you really feel about him since it most likely will not hurt him or make him feel bad but only give him the feeling of control and power in the situation. "He who angers you, conquers you!" Instead hit him where it hurts and since he was in prison he most likely is on parole and has probation expectations. Find out who his probation officer is and have a little one to one with him regarding his current actions and fear of what he may do. Your daughter may feel pressured into seeing him so I do suggest she talk with someone and seek legal assistance.
