For anyone who needs to hear it right now: he’s not going to find someone better than you. And no new girl is going to do the things you did for him, and he’ll realize that. Maybe not right away, but one day he’ll wake up at her apartment and there won’t be coffee waiting for him and he’ll realize how much you actually did for him, and for a brief second it’ll hurt him, right in his chest. And no matter how quickly he moves on, no one will know all the things you know about him. That’ll take years. And he won’t have the level of comfort he had with you and that’s noticeable. And at first, new things are exciting but that wears off and he’ll realize all the stories she doesn’t know and the years worth of inside jokes she wouldn’t understand and the tears she wasn’t there for and all of a sudden his new toy won’t seem so shiny. You aren’t replaceable and you aren’t expendable and you aren’t forgettable. People leave and they move on and sometimes it’s a mistake and sometimes they realize that. But sometimes it’s not and sometimes you both have separate happy endings.
