4. You’ve shown each other a full spectrum of emotion
You’ve horrifically, properly, full-blown cried in front of him (Clare Danes in Homeland style) and rather than be terrified by the apparent melting off your face, he just listened, held you, and tried to make you feel better. To be the forever one, one must be true in front of each other. Not hiding emotions in one of the things.
5. You’ve talked about your plans and are on the same page
Sure, you both know that you love to lie in and watch a rerun of Take Me Out on a Saturday but if you don’t know either he doesn’t want kids or if he too wants to live in a house in the city for five years at least, then you don’t know shit. You should know where the relation is going.
6. Even when you don’t like him, you love him
He might not always say or do the right thing (but then again, neither do you) but even when he comes back from watching the football reeking of cider and trying to tell you about how amazing Rooney is, you still love him. Even if you wished he would just leave you alone and let you sleep.
