Hi sis, sorry to hear about this person trying to upset and discredit you in fb. My advice, don’t let this lowlife get to you. Once you see sarcastic comments or hate mails, delete it and block this person right away. Don’t even exchange hate mails because you’re only giving this person the satisfaction. You got better things to do with your time than to stoop down on this person’s level. Just carry on being happy with your life and with your man and don’t let this person affect you in any way or at all.
