Mine was immediately after high school. I had trusted the person do much and we could share almost all the secrets. Whenever we had issues at home, I used to share out with him. He was my firys first love and didn't know much when it come to relationships. By then, I didn't see anyone else apart from him and everything he said was perfect. There's this day we had a short argument and didn't know it could turn to a big scandal. The guy turned against me and used all the secrets I used to tell me to abuse me. He abused me of my family and this made me cry bitterly. I couldn't control myself because the pain was so bitter to swallow. I talked to my mom about the matter but indirectly and she's the one who consulted me and made me feel better. I was so much heart broken and swore never love someone with whole my heart. The most important lesson that I learnt and can help you as well is that, you should never pour your secrets to friends or partner. No matter how much you trust them, human beings aren't trustworthy.
