How can I get my mind off this?

I recently “lost” a woman I really loved because I was too annoying. I learn from my mistakes, and I will take it slow next time…

The problem is, I’m young, and I know I’m too young for a relationship! But I can’t stop thinking about different girls, how sexy they are, and especially that one woman whom I’ve annoyed. I got video games, read long books, and tried different stuff to make the time pass, but I can’t wait for years before I can get into a relationship…
My question is this:
What should I focus on, and make my main goal in life, if so far all I’m thinking about is getting a girlfriend? How can I keep my mind off of this for years?

I seem to have this urge to be nice to a girl, but the first (previous) woman I loved got annoyed by too much of my “niceness”. I want to care about a girl, make her feel special and loved… even though I probably don’t understand the true meaning of love…

PS. I don’t watch porn, or masturbate, which makes this so much harder to not think about!

PSS. I know you’ve been curious, so I’ll tell you. I’m 14 years old.
