Broke up and trying to be friends

Hii, so my boyfriend of six months broke up with me like a week ago and we've been trying to be friends ever since and we have some good times and it's fun but it's also really challenging for me because I still love him like a crazy amount and I haven't been able to let go of these feelings even the tiniest bit. I miss the times of us dating and it was really good for like the entire part except the last month things had started going downhill. It still hurts a lot to think about and I'm trying not to and just be friends but I can't help it. I still love him a lot and it hurts when I even have a feeling that he's already getting some other girl or something and has just moved on really easily, which I know isn't the case but I'm super paranoid about it and I just don't know what to do. I'm scared to go through life without him by my side as my boyfriend honestly.
