You are 18, and I know you probably don’t quite feel like an adult yet, you are and you’re allowed to go on trips with other people by yourself. You don’t need your dads permission. It’s honestly even more gross that your dad doesn’t even allow you to hang out with your mom.

The unfortunate thing is that he might kick you out sooner than you’re ready, so I would think about how you’re going to separate yourself from your dad, because you’re going to have to be independent eventually. But I can guarantee that you do not want to be 24 and still have your dad control your life like this.
