AIO for being hurt that my boyfriend is judging me for my past he already knew about

So here’s what happened. My boyfriend was looking through my phone memories and came across an old Snapchat story from when I was 16-17. In the photo, I was taking pills and Xanax and I had marks on my neck. It was taken during one of the darkest times in my life. My dad had just walked out, my mom lost custody of me, and I was living with my grandad in a shared house with basically zero structure. I was at a lost and dealing with shit in an unhealthy way. He sent me the photo and basically said, “I knew you went through a bad patch, but I didn’t know you were popping pills, doing Xanax, and hooking up with guys.” He said it makes him question if he should even be with me now.

I get that the image was jarring and maybe even upsetting, but I’ve changed so much since then. I’m not that person anymore. It hurts that he would use something from such a painful time in my life to judge my character now especially when he knows the trauma I was dealing with. On one hand, I get that it might be shocking to see that side of someone you love. But on the other hand, I feel like it’s deeply unfair to hold my past against me when I’ve grown and healed so much. It’s making me feel ashamed of a version of myself I already struggled to survive. am I overreacting for being upset about his reaction?
