Forgetting him

I was with my boy friend for years .. I always felt he was not happy with me . I tried my best to give what I could . my parents don’t know about this relationship. we both are from different countries. I didnt had any problems with adapting to his culture but I needed time to understand him. I m going to 21 . he is 21 . he asked . lets get married. I told him I needed time like a month or something because my exams were going on.. I m a student and he is not studying as in he does not want to go to college. he just finshed his high school thats it. so during that exam period we talked and I thought and all that. we had fights and all. he stopped calling me like a week. after my exams when I called him , he told me he is with some gul. I told him leave here and come back. he said I don’t know . I asked why you did this you cheated on me and all.. he said to me I didnt call him so .. he said he is not guilty of anything.. now we are off.. bu he calls me something when both have a fight and all. he says to he his coming back . but then later everything is normal. now he is happy with her and tells me that what I wanted from u .. I m getting from her.. I don’t know .. I m just confused . I want to forget him . at the same time I feel whats was missing in me. that he left me.
