repeat after me

It's weird knowing that the person you're with now wasn't always yours and they've done the same stuff with you as they've done with other people. They've fucked other people, laughed with other people, joked, cried and shared lasting memories. You just wish you were the only person they had ever done those things with and continue to be the only person. These thoughts make me want to vomit. The thought of you with someone else in the past makes me sick.
