Please help me !

So I use to дата a guy then he сказал(-а) we are better just like friends. so now we're just Друзья but what he doesn't know is that I still Любовь him. Everytime I see him and everytime he talks to me I feel like i'm gonna breakdowm. And the worst part is that he's dating another girl.
How can I get over him ? PLEASE HELP ME :-(
