Someone who knows you very well, and it scares the crap out of you. however, you love them, you are there for 'em, they can cry on your shoulder, you can laugh so hard you're rolling on the floor with them, you can't be mad at them even if they really mess things up for you or for themselves. they know your secrets, they understand the way your weird brain works (and who knows why, they LOVE it. creepy, i know), they surprise you and at the same time its just so easy to be yourself with them, no shame, no awkwardness, no waiting, worries, just total understanding.
if your boyfriend is your soul mate, your a damn lucky girl.
some believe it, some say its shit.
beware. when your in, no way out.
