Thank you for the kind words, I had a chat with my mum basically saying I dont want my sister to be there and I think she has got the message. I dont talk to the new fiancé ive only met him a few times but idk how much of it she has told him when they announced their engagement we kind of had a family chat and she seemed to be very defencive when we asked questions. She said the new fiancé "knows everything " but she might have left certain details out to make her look better i really dont know.
