Hello, it is obvious that this person is really scum. Whether he really loves you or not, he cheated on you and you broke up, so don't contact and think about him. As for the girl who added your friend, to be honest, you'd better hack or delete it, because everything related to him will only make you more sad. I once met love rat, and it was painful to break up at first, but I forced myself to forget, delete all his information and stop contacting him. It will be fine after a long time. I have met my own happiness now, and my boyfriend is really good to me. You have to believe that as a girl, you must have a bottom line and dignity, know how to love yourself, and others will respect and love you.
