I feel like a bad gf

I looked at someone multiple times because I found them attractive and now I feel like a horrible girlfriend. I only want my boyfriend and I adore him so so much that I’m terrified of doing something wrong. I looked at this person quite a few times and I feel disgusting! I only want my boyfriend but I don’t want to tell him this even tho my mind is telling me to. I don’t want him to think I’m a horrible girlfriend
