I have a crush on one of my guy friends but he has a girlfriends and she is really nice and they are basically perfect for each other, but I can't help liking him. He is sweet,funny,caring,most adorable, hot as 🔥, isnt all about himself, and just basically perfect. 
I think about him all the time😍😍 and we talk pretty often. 
Does anyone has anytime on how I can fight against liking him, and i don't want to give up him being my friend
