If she's going to be a bitch and just ditch you like that, then fuck being with her. It doesn't matter how many times she said she loves you, because at the end of the day, love is just a word. She obviously doesn't love you with her heart. Find a girl your age who's mature and can be there for you. Not some little 10th grade bitch. Anyways, best of luck my friend. Wish you the best.
