Absolutely nothing wrong with that, Screwtape. In fact, I don't think anyone would argue that point. Everybody, at some point, is looking for a soul mate, someone to share your innermost feelings with, someone to be your best friend as you get older.
But, you need patience with that. It takes time to find that special person in your life. More likely than not, it doesn't happen on a whim in high school.
Trust me, I know this, from personal experience when I was 18. I used to think the way you do. It just doesn't pan out the way you are hoping it does. Not at that age, at least.
Don't worry, though. You'll go through it soon enough. Nobody ever really knows what it's like until they experience first hand.
