I really liked this guy. He was my best friend for a really long time. My little cousin started talking to him. She didn't know I liked him, thought we were just friends. In December they started dating. He just turned 17 and she's not even 14 yet. They had sex after a month of dating. I'm honestly so broken. Its been forever since I talked to either of them. Me and this guy went through a lot. He was my neighbor and when he was about to hang himself I was the one there. I helped him and hugged him. I miss him. Any advice on how to get over him will help. I'm sick of being broken. Its been almost 6 months. Please help.

UPDATE: Her parents know they are having sex, her mom didn't care. She just got put on birth control.
