Help me im so confused?

my boyfriend broke up with me earlier today and i've been a mess ever since. he said we could still be friends but i dont think thats gonna happen. i cant get him off my mind and ive been crying for hours. not only that, but i was stupid enough to tell another guy i would go out with him so now i have a boyfriend i dont really like that much and a lot of heartache. can someone please help me deal with this he was my first boyfriend and i really really liked him.
