Is there a chance? opinions pleaseeee?

me and my bf were together for 6 months. we had a few breakups during those 6 months and he would always beg me to please just keep this working because he loved me so much and i was the only good thing that happened in his life. he just recently ended it because he always worried about me hanging out with my friends when other guys were there or texting other guys and i always thought it was just him, but the more and more i think about it i think it was my fault and i should have considered his feelings more. he told me now he's tired of worrying and its really hard for him but he just wants to move on and he is starting to like someone else already but if that is true i just think its because he is having a hard time and is seeking comfort, but maybe im in denial. do you think there is any hope in the future to rekindle love? i only want to be with him. i love him with all my heart.
