I think I should confess my trauma to my boyfriend's parents
Is this about something from your past?
Yes, I'm planning to tell them that I had a hard life and that I felt alone
It's okay to share feelings and experiences that cause you a lot of pain. It will help you confront and learn about the past and look ahead for a better future.
Ah shit his dad doesn't like me. Once he finds out about this then he will end up taking sexual advantage of me.
If you really think your boyfriend's dad will take advantage of you, or if he already is taking advantage of you, then you need to tell someone about this. Talk to your boyfriend about how you're feeling and contact the police if his father is already abusing you.
