the good times you feel with her, those will be even more powerful when you find someone who your truly meant to be with... dump that girl... if she comes back to you, LAY DOWN THE LAW. the good ol saying, If you love it, let it go, if it comes back to you, its yours. trust me bro. let her go and if she wants to come back youll have a better version of her. if she doesnt then you need to just focus on improving your abilities for the next girl. Surely you have a passion for something whether your good at it yet or not, start practicing, take out your emotions on whatever your practicing and become the best in the world at it. I believe in you.
