i was married when i was 25, because i fell into the trap of "you have to get married" I am happily divorced, and will never get married again, nor have children. Why-because I do not think that to be happy you have to get married.
I do live with my bf though, but honestly i even question if i am meant to be in a relationship at all. haha.. i can't just pick up and move when i want. I also think some of us are meant to have it for a brief time and move on, i tell people i am like marry poppins, when its time to move on, i will.
