Peach is potentially a dangerous person because controlling a partners Facebook profil is a clear sign of a destructive form of jealousy. Chances are that he is insane in his mind. This level of jealousy is potentially dangerous and if you had not left him already, he would probably has started using violence to get his way. For your own good and health, please make sure not to talk with him
I am not sure if you know this Tangmo, but some Thai men's behavior in a relationship is life-threatening for their partner.
Hello Tangmo. Don't worry. Peach is out of your life now! You will not have to pay attention or talk with him ever again. Please just ignore him and as time goes by, he will realize that he has lost you for good
