Super Hot Guy Making Me Question Everything

So I’m in this class with this like absolutely gorgeous guy, and he’s sweet and he compliments me. And me having a crush on him is making me question whether I really love my SO of over a year. It’s just my SO rarely tells me I’m beautiful and the sex is amazing but it’s rare which makes me kind of annoyed. I don’t know I just feel like me having a crush on this other guy is so shitty and I feel sick to my stomach for even thinking he’s hot. I love my SO and I want this to stop but like the guy is in my class and we do work together so like I don’t want to be a dick and ghost him. I don’t know I feel like I’m back in high school rn. Advice?
