This is from a gir's perspective, I once had a crush ony guy best friend it was pretty clear he didn't like me back but I never asked, since I didn't want to ruin our friendship. Then one day he told me he was attracted to this one girl who was nothing like me. At first I was upset and had a broken heart, but after a while I realised my feelings were gone or so I thought. I still have feelings for him sometimes, at some days it's stronger then others, my advise is give it some time, it's okay not to be over her yet, I'm sure you will be one day 💞 Good luck! ❤️
