help me :((

in my 8th grade year (im in 10th now) my ex boyfriend (who was 18 while i was 13, i know i was stupid) took advantage of the fact that i was so small and helpless, and he was a lot bigger than me. i was probably around 90-100 pounds then, and he was possibly around 150-200 between there. my parents didn't believe and told me i couldnt press charges, but i see him everyday because he lives down my street and always goes running. this happened april of 2017 but im still terrified of him.

hes a nice guy, he always has been, but he just does stupid things. but he wasnt abusive, he wasnt rude, he was overall really sweet. i dont know what happened...
