Cheating?

I’m in an LDR though I’m 14. We met online and he became deeply in love with me. I’ve tried multiple times to tell him I’m not happy and he breaks down telling me he doesn’t want to lose me. We only see each other 3 times a year and I don’t know what to do. I’ve been with him for over a year now.

I love him so much and being with him makes me happier than anything else, but during high school I’ve run into so many new people and my mother wishes for me to date other people, but I feel confined to this LDR... I don’t want to break up with him, but I still wish to see others on dates and dances. He considers it cheating... I sort of do as well. But none of my relatives do.
