Crush

I am 18 and i have a broken heart. i have had a crush for over a few months, i knew the guy for over a year, he once asked me out and told me he would date me if i went on a date with him. I told him yes i would once i would comeback from a vacation i had. Any ways days would pass and he would not call me or text me untill alot of days later. And then one day he just got mad at me and told me that i just hurt him alot. I do understand how i hurt him but i know that i have a broken heart and cannot seem to get over it and i have no clue how to. I feel like my life is over :'(
