Should I forget him and how?

I am 19yo japanese girl and was seeing a 21yo serbian who met during my study abroad in Serbia.
I broke up with him last week because I love him but long distance relationship made me can not see the future with him.
I know I did stupid thing
shouldn't I have told him break up with me even I see no future with him?
( I am sorry that my English is difficult to understand
