Have a bf but have a crush on another guy

I’ve been dating my boyfriend for two years and we go to different schools. I go to Ohio state and he goes to penn state where he is an athlete. There’s always a ton of girls on him and it makes me so paranoid and I’m always worried. Literally every girls wants him and I’m FIVE hours away.

I have a crush on a guy here, and it’s lasted for months. I even told him this when I was drunk. He always flirts with me and everything, but holds back because he is a gentleman and knows I have a bf. my bf is familiar and I he knows everything about me, there is no one I’m more comfortable around. BUT why do I always think about this other guy?!!!😩 Am I subconsciously losing feelings? Is it possible to have feelings for more than one person ?!!
