Dream about a girl I love?

OK I have a dream every other night about the girl I love and in real life when play Xbox 360 games like wwe or Sims or any other games I have to make her on the game and she's on my mind 24/7 she recently blocked me on facebook and all I sent her was this she tried to get me to ask this girl out and i said So and I already am going after one. here is what she said Who ? This one is the one she will rock your world. and she asked who I'm going after and i said u destiny and even if u never likes me or careS about me I'm going to love u for ever and ever for the rest of my life no one else matters. Then I sent her this u have the most beautiful day ever and may it be more beautiful than a sunset then she blocked me how do I get her to unblock me and I thinking of asking her to marry me would that be a good idea to ask her to marry me
