Why do I see him everywhere I look? *READ*?

I see him a lot. Some times it’s him, sometimes it isn’t...
basically, my mind adjusts to it and I see people when I’m out in the dark and I’m like “OMFG THATS HIM” and I go after them and it turns out it isn’t... every man I look at (usually from distance) looks like him and I’m starting to wonder if I’m really that besotted? I need help
