I think the scary part is that eventually we all become strangers and the body you used to let yours sleep against only two months ago now silently tells you to keep distance.
I think what hurts the most is that you used to look at them and know exactly what was going through their mind and now the only thing you are sure of is that it's not you.
You used to call them when you felt like **** and now you're fighting yourself all night not to dial their number.
They used to fill your mind first thing in the morning and your mouth would easily curl up, now they're the last thing at night you think about and maybe you have never even known eachother.
