Is it weird to fall back into love with your ex?
Sometimes if you can't get them out of your head and you do have a good connection with them then it's okay. But if they aren't interested then don't pressure them to go back out with you no matter how much you like them. If they don't like you and don't want to get back together with you then the best thing to do is try to move on and forget the past. Maybe later in the future you guys could become great friends.
