Dad Syndrome
When your dad doesn’t like your relationship and tries to make your partner’s dad hate you. It goes from ‘meh’ to ‘you’re not allowed to see your kid’.
My dad told my girlfriend’s dad I was a bad influence. He got banned.
My girlfriend’s dad didn’t like me, and now I’m banned from seeing her.
My dad went full-on ‘you’re not allowed to see your kid’ because he didn’t like me.
