I think i'm obsessed with marriage. (please read!)?

First i'm gonna start by saying i'm only 18. I fantasize about meeting that perfect guy. I have never had a real boyfriend before honestly because no one fits me..... My parents were never married and i'm not really close with my family so i'm really anxious to start my own big happy family. I want the whole 1950's picket fence kind of life. My friends tell me that i need to just enjoy being young but idk i can't get it out of my head!!
