Always you

I always come back to you, it confuses me because I don't know why. You're always there for me no matter what, you said that's what unconditional love is. You never pressure me, sure you can be a d*** but no more than I, or anyone else can. So why, why is it i always run away from you? Why am I afraid to love you? 13 years I've known you but am to scared to truly let you in.
