Hello mosp.
You need closure. This is tormenting you and you can stop it. There are two ways to go about stopping it.
Therapy and coming to terms with the fact you will never get that apology. Never get answers. It won't happen.
Or you can choose to find your voice. The voice of one that was assaulted and carries it inside. You can tell the whole world what he did if you want. You don't have to protect anyone but yourself. Nor do you have to answer to anyone but yourself.
However. If you choose the second option you would need to be prepared for the fall out. Those that find out may not believe you. They may be hurtful. You might not feel better for it.
You need to work out what's for the best and I'd advise a professional to help you decide what you need to do to get closure.
I went for the second option. I messaged him on Facebook. He didn't respond. Then I outed him in Facebook. Reason being I had all my family on my fb and so his too and I wanted everyone to know what he was.
The fall out was huge and unpleasant. But that has settled down now and shown me who should be in my life and who shouldn't. I cut a lot of people off and have closer bonds with others. I don't regret it for a second and I'm proud of myself for standing up for the child I was when no one else did. I no longer have certain people in my life but I haven't lost anyone but they weren't worth losing.
I had counselling throughout however.
One thing that may help is to try to think about what you would want your dd's to do if it was them. As a mother I know what I would do if god forbid anyone hurt mine. And I know what I would want them to do too.
If you go for the first option you have to follow it through. Ensure he can have no contact with you whatsoever. With therapy work on accepting that people don't change and they won't do what's right or what you would like. You can change however. You can change how much effect you allow them to have on your life. That is where you have the control. And once you get there any intruding thoughts or questions you have to learn how to put them out of your head. They are only thoughts.
And please don't think about ending anything. Why should you be the one to feel that way whilst he gets on with his life. Focus on you and believe in karma. I know I do.
