How People Handle YOUR Memories

I am really at a loss. Earlier my boyfriend scraped his fork on the plate and a major memory came to my mind. I was a freshman in high school I think. It was before my parents divorced so it was either summer or soon after school started. We were out as a family for dinner. Dad hated it when we scraped our silverware on the plate. I accidentally did this, and I remember looking at him wondering if he was going to beat the shit out of me right in the middle of the restaurant. He didn't but I got a look like I would be in trouble when we got home. I think he forgot because I was safe that night. 

Tonight though, Eric did the same thing and the memory of that night at the restaurant came flooding back. I tried to explain it to him and he told me I had too much drama in my life. He didn't want to hear that the simple act of him scraping his fork on the plate brought terror into my mind. I am pretty open about my past. There was a lot going on. I wasn't looking for sympathy, but I needed him to understand how terrifying hearing that was. I did speak to someone about starting online therapy. I mean, the scraping of the fork set into motion so many different emotions. Will I ever be able to get all of this worked out? Will my past ever be resolved to where I feel normal?  I am 60 years old. I want some time of normalcy before I die. We'll see.
