Dear Roo
Hello and welcome to the forum. I join Quirky in apologies for letting your post go unanswered for so long. It's not good and certainly no reflection on you or your post,
No one deserves the horrible things that have happened to you. It's definitely wrong and I feel so sad for your life and the misery it has brought you. As Quirky commented, your partner does not find you miserable otherwise he would not stay. Rightly or wrongly I presume he loves and cares about you. Do you have any children?
I think when someone has been exposed to such awful abuse they often feel it must be their fault. Why else would they be picked on. Not at all true. There are bad people who prey on children and other vulnerable people. It's certainly not their fault just as it is not your fault.
I can understand a little how unloved you feel. No one can fully enter another's emotions and know all about them. We all have our own experiences with their attendant joys and hurts. What I do know from my own experience is that being happy is hard work. All the bad things that happen can so easily swamp and overwhelm us until it seems there is nothing good ever going to happen.
Can you think of any good thing in your life? I imagine it has been good to meet your partner and be loved by him. What else can you think of or remember? Small incidents can mean a lot. I remember going to the cinema with my boyfriend and sitting there with his arm around me. I felt loved and happy in that embrace and as you can see, I have not forgotten it. These small joys give meaning to our lives and each one contributes to our happiness. Can I ask you to think of any occasion when you felt cared for no matter how small the event seems.
Make a list of these moments and re-read them often. It is good to remember no matter how long ago or how small. I remember my dog putting his head on my knee when I was unhappy. That gesture made me smile and hug the dog. They do know when you are hurting and offer their kind of comfort. Do you have a dog or any pet? Maybe you could consider this.
It seems to me you need someone somewhere to listen to you recount your story. To help you explore this dark time and help you to let it go to live a happier life. I know this will not be easy. I know my experience of utter betrayal had me angry with just about anyone. The trouble with this is that it only hurts me or you. Those who have harmed you probably don't care.
I have run out of space. Will write more later.
