Real crush at the age of six? I wouldn't call it "crush."
WOMEN! (i'm referring to you Kylie) I just don't get them.
I cannot emphatize. I thought most women like being given flowers (my sister does)and being treated nice. Well, you've proven me otherwise!
How about lowering your standards! Are you afraid of commitment? Were you hurt really bad before when you gave your heart to someone or when you were dumped? Because sometimes, people try to build a shell around them to avoid being hurt again.
"He hurt me so bad, I don't want that feeling. I'm going to keep my guard up, so the next man won't be able to hurt me."
The problem with this is that one shuts up their door. Even their heart. They won't let anyone love them, as they think it would only lead to suffering like what happened before.
My guess is that your previous relationships didn't last long.
You see, YOU'RE NOT LETTING YOURSELF TO KNOW THEM DEEP INSIDE, or know you. You're not giving them a chance. Take some time.
