Is this safe or am I overthinking it?

I keep thinking about my childhood and I remember this one time my cousin stayed with my parents and me and my brothers so being the fact I had my own room my mom told me to sleep on the couch and my cousin took my room. But I was 7 years old and one night my cousin had her bf at the time come over and I guess my mom knew I don't know. Anyways he stayed the night with her and all three of us stayed up to watch tv and my cousin was in the middle and she fell asleep. We were on the floor and I just remembered her bf said my name and I looked at him and he just smiles and looks away. Did I feel uncomfortable? Yes yes I did I don't remember how that ended but I'm shaking a little so it must have effected me somehow
