my boyfriend's sister has once again started drama she unblocked me on fb I was able to see her name on her moms page when her mom added me then she blocked me again so I search for her come to find out shes talking about me my relationship and her family members and other people that she "hates" I called her out basically on twitter and what does she do deletes all her accounts lol and then goes on to talk more and say on her page that she makes people things for that im bitter and she has to "Deal" with me again when I didn't even do anything to her why is someone's sister crazy like this and plays victim and runs when shes called out seriously now im afraid his mom will think im the bad guy when shes done in this past
shes said sorry before but then turns around and starts this drama again she acts like an ex girlfriend and its very strange that someone will go to such lengths to attack me when she doesn't even know me

Just talk to her and tell her that it's bothering you and that she really need to stay out of your guys relationship

It's possible that she is very close to her brother and feels you are putting them apart. Have a discussion with her, and maybe pay more attention to her, so that you guys can bond and see your similarities. Maybe you can taLk to her together with your brother. Good luck!

I have a family member just like this! Hopefully if you're lucky (took too many years for my family to realise) then her family will know what she is truly like and ignore her immature comments. I would do my best to ignore what she says, just be nice when you see her, don't say rude things about her and just be yourself around his family. They will eventually realise the truth if they don't already

Forget your boyfriends' mother an sister because you are not dating them. The only thing you need to do is to focus on your boyfriend. The only thing that you no longer get involved with is communicating with them by Facebook, Twitter, phone etc. Let them talk about you behind your back. If you ignore them, then they will get fed up and they will stop. You don't owe them anything.
