After a fresh break up, you and your ex are not enemies nor are friends. Just two strangers with memories. But when an ex offers the friendship card, I say do not take it especially if they are the ones who left you. When they broke up with you, they lost you. They chose to cut the cord between you two and broke your heart. Now that they're gone, they are no longer part of your life. Their part in your life, that chapter, is now over. It's time to write a new one with someone deserving of you.
Them offering you friendship is like a consolation prize to cushion the blow of them leaving you torn in pieces. You are better than that. Sure you still love them and in a heartbeat will take them back. But are you ready to go back to that emotional and painful merry go round over again? If they really loved you, they would've suck it up, stuck by you, and did their best to work out the problems to keep the relationship going. But they didn't. They chose to leave. Sure, they might still have feelings for you and love but those are not enough for you to take them back even as friends. How can you be just friends with someone your heart loves and yearns for? With someone you long to kiss, to hug, to make love to and build a future with? Will you be able to take listening to them bragging about their new love and how amazing the other person is?
Friends do that and they are genuinely happy for them with their blooming lovelife. But are you happy for him? Or you wish it was you dancing with him instead of her? Do you want to be that person they call when they're bored or horny because they know you''ll always pick up the phone at wee hours? Do you want to be that back up person when they got rejected or dumped by their rebound? While you are busy fantasizing on the shoulda, woulda, could've your ex is out there banging someone new. Simply because you want him to realize you will always be there for him when he comes back as his friend. Enough!
He left you and you should change the locks to your heart no matter how hard it gets. You will eventually get over him. Do not be his friend! Maybe when you are finally healed from him then you can be. But for now, NO. You don't owe him anything. You owe yourself an apology for being a doormat to someone who thinks you're convenient. Do not be someone's option. Be someone's special one and only priority. Do not fall for your ex's ghosting games. They can stay dead. Denying your ex friendship is not immature or selfish. He is no longer your problem but someone else's. Fix your broken heart by loving you. One day, you will be happily in the arms of the love of your life, and you will see your ex... You remember the boy, but you won't remember the feeling anymore.
