My hair color is nice but I am just getting sick of it! I need advice... What color should I dye my hair?

There is this guy and he means everything to me! I want him to know that but it seems that he won't listen to me. I hsve already tried to talk about this with him but he never seems to talk back. He is my ex, but I want him back so bad... We have both made our stupid mistakes. He has a horrible girl that lives with him and that is his recent ex-girlfriend and she is getting in the way of everything! She is oober jealous if me and she always talks about me and she doesn't even know me. You could call her a bitch but thst would just be sinking to her level. Anyhow, I just want him back and I was hoping that some of you may be able to help me... Please, I need all of the help I can get!
