What do I do?

Lilly

So me and my boyfriend have been together for almost a year and a half, we are long distance and in high school. I am feeling guilty because in October me and my friends went to a haunted house place. I feel guilty because when we were in a really dark skinny tunnel in the house we were in a follow the leader style line and my acquaintance guy friend was in-front

of me and I held onto whatever shirt or sweatshirt he was wearing a little bit because we couldn’t see at all. Then there was a time in the haunted house when the floor felt like it was about to fall out from beneath us and we all got super scared and he was next to me so I grabbed his like shoulder for stability for a moment. I just feel horribly guilty about it because I think I might have had like subtle feelings for him, but I also have a hard time figuring out the difference between platonic and romantic feelings, but whatever I felt for that guy was subtle and I definitely don’t feel it now and haven’t since then. Should I tell my boyfriend? I just feel so guilty but maybe it would be better to keep to myself.
