Hello SadFather and a wistful welcome...
Do you know why they are being so abusive? What is their motivation? I do not have a traditional family like you do, but I can say with reasonable certainty that I tend to attract abusive people into my life. I was abused by a "big brother" type friend next door. He was really nice to me and schmoozed my mom to no end - allowing him full access to me. When we were alone, the clothes came off and there was really no saying "no" to him. Sounds like your priest.
And so I STILL attract into my life abusive people. I am convinced that it goes right back to my "big brother" years ago - the secrecy and shame and low self-worth - it's like we learn to accept it and even seek it out in our lives over and over on so many levels. People often talk about re-enactments of the sexual aspects of their abuse, but I contend that many of us are acting out on so many other levels and maybe don't realize it - even in our professional lives (as is my case right now).
You say, "i think if they stop the thoughts of priest will go away." I can't help but wonder if you'll find a greater truth by looking at it the other way around.
