ps - if your ex really loved his new girlfriend he wouldn't need you to validate their relationship, he'd be in his own happy world with her, not worrying about what you thought. ignore his childish games. he lost you and he's not going to like having to give up control over your emotions and self-esteem so the best thing you can do is recognise that he's clearly insecure to need to feed off bringing people down and smile because you're above that.
