I need advice!

My 8 year old attends daycare in the summer. The daycare is about an hour away from my job. Whenever her grandmother is available to pick her up early, I let her because I feel bad my daughter is at daycare for long hours at a time. Yesterday her grandma picked her up on her way home from work. She had to work a second shift at her second job and left her with her son (my daughter’s uncle) who is 18 years old.

Yesterday I was able to get off work early enough where she wasn’t alone with him for a long time. I did not agree for her to stay alone with him because I have some trauma from my childhood where I don’t trust anyone with my children. Especially males. I picked her up and she was fine. We talked about her day and I FaceTimed her while I was on my way to get her.

Well, today happened the same thing. But today I couldn’t get off early. She was alone with him for an hour and half. When I picked her up she was smiling and seemed ok. When we got home I asked her what she did at grandmas (I always ask her what she did at daycare, grandmas, etc so this is not new to her) she said “I don’t want to tell you” that gave me a huge red flag. So I asked her again, “what do you mean? What happened?”this is where I got worried. She freaked out and yelled “im not telling you!!” I reassured her that she can tell me anything and she can trust me. After I said that she got up from the couch, crying and ran upstairs yelling “I’m not telling you ! I’m not telling you!”

I need to make sure it’s not my trauma kicking in and assuming the worse. What does this sound like to you???
