Thank you for writing. The abuse of a child by a trusted adult is shattering for the whole family. Every relationship in the family is damaged. No one knows who to trust anymore. Your daughter can’t trust her stepdad. She may wonder if she can trust you since, from her point of view, you didn’t see what was happening.
You can’t trust your husband to be alone with your daughter because you have no reason to believe that he won’t do something else to hurt your daughter. Your husband may wonder if he can trust himself. He knows what he did was wrong but he did it anyway. And you may wonder if you can trust your own instincts since you didn’t see this coming.
You were right to ask him to leave. You were right to immediately get counseling for your daughter. And you are right that you need counseling as well. Your own history may have contributed to your inability to recognize that his interest in your daughter was crossing a boundary. Further, It is not unusual for the non-offending parent to both love and hate the abuser. The things you love about your husband are still there but without trust, you know don’t have a relationship. It will take concerted effort on his part for you to let him back into your lives.
I hope your husband is not back in the house. He shouldn’t be. Not until he gets intensive treatment. You have the right and obligation to insist on it if he ever wants to be alone with your daughter again. He has not been a “good father” to your daughter. His violation of the most important boundary calls into question any positive influence he may have had. Your daughter will struggle with that issue with her therapist.
Before you let him back into your and your daughter’s life, you should also go to couples counseling with your husband. Navigating the challenges of rebuilding trust to the point where you truly believe your daughter will be safe is very difficult to do without the support and coaching of a professional.
I wish you well.
