Made the biggest mistake of my life when I made a girlfriend. I loved her and gave her everything I had. We dated for 3 years, were gonna get married in 3 more. Then one day she left me for another guy. And I have been a miserable ******* to everyone ever since.
I play this song whenever I think about her https://www.youtube.com/watch?v=Np2_9JcVZaA
Well, some girlfriends in your live you will love more and others you will love less. As you are young, you will learn that when you get older and always change your girl friend.
As you seem to walk in the dark side of feelings at the moment because of your last not successful experience, you best stop watching TJ, go out and get in love with the next one. Maybe that will be the one you will share the rest of your live with instead of listening to that, sorry, stupid song and fall always back into self-pity. Nothing personal, just a wake up call.
