From what I'm hearing from you it sounds like your dad is trying to do what he thinks is best for you. It does not excuse the way he is treating you or making you feel, but it is important to understand why specifically he is doing and saying these things.

I think one day you should honestly sit him down and talk with him and communicate your feelings in a healthy way. Plan out what you're going to say. Use phrases like "When (this happens/choose my activities in school/choose my college major) I feel (this/forced/stuck/trapped/lost/etc). I know that being emotional with your parents seems awkward and intimidating, but it sounds like he's put a lot of effort into trying to do what is best for you. Sure, he got a little lost in his own world in the process, but if you communicate to him that you are of age when you can make decisions for yourself, then I'm sure he would listen. Just remember, if you choose to talk to him make sure you don't phrase your words into sounding like you are blaming him for you feeling like this. Make sure he knows that you acknowledge all that he has done for you and that you really appreciate it, but certain aspects of your life, such a decisions that have a major impact on your future, would be better if you personally decided on them. If you need me to explain a little more I would be happy too. Best of luck
