My cousin's boyfriend (now ex) kissed me and he grabbed my chest. Um she still doesn't know, i think? I was 16 & he was 20. She was also 16. A 4 year age different wasn't that of a big deal to me then. Now we're both 17-18, we both aren't in touch with him because, he's a creep. We heard that he hooked up with a 15 year old girl that I know, he's 21 or 22 now. Advice?
