You dumped him but now you want him back. On the face of it, that should be easy. Won’t he be happy and pleased?

Well, it’s a bit more complicated than that.

You may have an uphill task on your hands, because now he is in the position of power, not you. And even if, up to now, he has wanted you back; this might change when he knows it’s what you want too. He may decide that, now he can have you, he doesn’t want you after all.

Don’t start chasing him.

Leave a space for him to approach you. You need to be subtle; and keep your dignity. Don’t make an emotional speech about how stupid you’ve been. You dumped him, but now you want him back. Let him be grateful.
