Help!!

I'm in love with my childhood bestfriend and I dont know what to do. Me and this kid have been bestfriends since I was in 4th grade and now I'm currently a junior in high school and he is a senior. I've always had a crush on him but I always pushed it away and ignored it until recently. 6 weeks ago we both confessed how we liked each other and it was cute and everything was great. I fell so much harder for him. We hung out about everyday doing the thing we both love the most, going to the soccer field playing soccer for a few hours than going to our spot laying down and looking at the sky as we talk until one of our parents called us to come home for dinner. These days and all our memories just made me fall in love with him. About 4 weeks ago he became really busy and started ghosting me so I did the one thing I know how to do I pushed him away and ended things. I found out now that he kinda likes this one girl because even tho the relationship part didnt work out I still love him and he is still my bestfriend so he still tells me stuff, so he likes this one girl and I'm really sad about it because I really like him and I wanna try a relationship again but I dont know if he still feels the same way. I asked him about it a few weeks ago and he said he kinda lost feelings after we stopped talking so now I know he doesnt really like me but at my birthday party 5 days ago me and him were flirting a lot, even my friends noticed it so now I'm lost and confused. After I ended things we didnt speak to each other until the day leading up to my party and everyday after that and all this stopped yesterday when he left me on read on snapchat. I need help I dont know what to do I really love him. Please comment advice!!
