He felt no love anymore and that's the end

My bf broke up with me suddenly just in one day. He said he needed some time alone and the next day he said he couldn't do this anymore. He couldn't feel the love he used to have for me. We were still talking normally before and I didn't see the sign. I was studying abroad, far away from my family and friends. People said it was because of the long distance relationship. I did my best keeping in touch with him. I would spend more time for him than going out but in the end, I can't save my love. I remembered before I left for my study, he said he could wait since he knew my education is important. Apparently, he couldn't do that. I did my best, I also felt lonely too but he would give up so easily. I'm still hurt so badly. I feel stupid for believing in his words. Fate, he said when we first met, but is it? After all, he had all of me, took everything, broke me and fled. I really want to know how to fall out of love just like the way he did, so easy like that cause it's so hard for me.
