I think so too. Take her statement that she doesn’t want to feel “overwhelmed” as the truth. She doesn’t want ever again to feel overpowered and out of control of what is happening to her. It is impressive that she has come so far that she is able to enjoy pleasuring you and to participate as a sexual partner. It’s only sad that her victimizer has deprived her of the spontaneous abandon and sexual satisfaction that can come with totally trusting one’s partner.
You didn’t mention if this has become a difficult issue between you. If it has, I suggest that you be as sympathetic as you know how to be. Tell her that because you love her and are married to her, you are also being affected by the crime. You hurt for her and you get upset that you can’t be as close to her sexually as you’d like to be. Ask her if she would be willing to participate in some couples therapy so that the two of you can work together to get the perpetrator finally out of your lives. Don’t pressure her. She already has had a profoundly negative experience with pressure. Do offer your love and support and your willingness to respect her pace. If she isn’t willing to work on it, enjoy the unselfish way she loves you and give her time. With time, she may be able to relax into your love as well.
I wish you well.
