I want to preface this by saying my mom is an amazing person who has given me so much. I love her immensely. My parents never had a happy marriage. For several years, my dad was abusive to my mom and to us kids (he drank and hit us) and I strongly resented him. As a teenager, I grew very rebellious - began sneaking out at night, smoking and drinking by age 15. My parents were both really worried about me and tried enforcing strict rules, which only made things worse. My bedroom could be locked with a key and my room was my haven during those years of constant yelling. At some point, I lost the spare key and looked everywhere for it with my mom. Then one night, I went over to a friends place for a sleepover. My mom called to check-in and told me that dad was drunk, throwing things and being violent. I was so afraid for her safety and said I wish I had left my key behind so she could lock herself in my room. I barely slept that night. Years later, I found out that my spare key was never lost. My mom had stolen it to snoop around my bedroom to ensure I was not on drugs or whatever. So she had the key the entire time and used it that night to stay safe, but she lied to me to cover up the fact that she was snooping in my room. I will never forgive this because I was so afraid for her while she was secretly safe the whole time.
