if you don't like her, why would you ask her out?
Now for my life lesson, hahaha.
Don't do something because somebody else wants you to. EVER. Although you may think that you will just do it to stop them or because you think it will make you happy. You know what will make you happy, NOBODY else. Don't let people decide for you or influence your decisions.
Now i am not saying that what other people say doesn't matter. But you need to take what they say, and use what will benefit you.
For example. You dad wants you to play baseball because it will help you get into a good school, but you only want to play because its fun and its good exercise. You need to tell him that you will continue playing, but not because he wants you to.
You took what he said, and you applied it to what you want and what will make you happy
