The weeks leading up to Christmas BM has been uncharacteristially quiet, silly me thought that perhaps she was finally mellowing.In Sept she sent DH an e-mail regarding Christmas arrangements this year (they alternate Christmas every year so 1 year SS spends it with DH & following year with BM,whoever doesn't get SS for Christmas gets him for the Boxing Day). Anyway in Sept BM stated she would pick up SS at 6pm Christmas Eve,DH said ok we would all be back from FIL in time for pick up.Every year Christmas Eve afternoon is spent at FIL.Come 4pm BM sends a text to DH "you are to drop SS to me,my family has arrived & wants to see him.At this point all SS and his cousins are all exchanging gifts.DH texts back "no you said you would pick up at 6pm", at this point BM starts blowing up DH's phone & SS's phone.DH doesn't pick up but SS does and gets a roasting from BM because she demands that he gets dropped to her NOW.She then texts DH "You will drop SA to me!!!". DH forwards her a copy of the e-mail from Sept she follows this up with "fine SS can stay until 6pm but you will drop him to me!" DH asks should he just drop SS off on our way home to avoid any more drama,to which I replied absolutely not, I am sick of her last minute changes & causing drama on Christmas Eve over something which was decided months ago.Furthermore had she said "Could you please drop SS off to me on your way home" then yes possibly,but being told "you WILL do this" just infuriates me -manners costs nothing!She has spent years talking to BM like he is a piece of dirt & he would just put up with it.So DH texted back "SS will be ready for collection from us at 6pm as agreed" & ignored the rest of her messages.Needless to say she picked up SS but wasn't happy about it,aah well to bad bitch!
