Bestfriends?

My best friend for over 2 years now is a guy, and we’ve been through a rollercoaster of 2 years. I wouldn’t change him for anyone or anything. However when I started my 2nd year of college, i made friends with this girl and introduced them, as me and her were very close friends and she thought my best friend was fit. At this time i had a boyfriend so everything was good and i thought we could go on double dates. However my boyfriend did not get along with my best friend and every time my boyfriend said something bad about my best friend we would argue because obvs i would defend my best friend. When my best friend finally asked this girl out he didn’t wanna know me and treated me like utter sh*t . She manipulated the whole situation so we’re not friends now. I’ve lost my best friend to a girl that he’s known less than 3 months. Before me and my best friend fell out, i started feeling myself get jealous of his relationship and someone else having him. For years now our mutual friends have said there’s something more between us and i always dismissed it but now i think it’s true.

I don’t if it’s just because I was the only girl in his life before and now i’ve been replaced and my feelings are confused or there actually genuine, i don’t think we’re ever gonna be friends again😕.

Do i tell him i like him? Is there anyway i could have my friendship back with him?

I need some help😫Has anyone been through this before??

PS- i’ve broken up with my boyfriend now
