I'm NC with DH's sister and her husband - they have been vile to me in the past and can be openly rude and nasty.
I'm a sensitive person and against the brashness and entitled behaviour of DH's sister , I do not fare well and it makes me resentful and bitter of how they treat me - I've gone NC and I'm so much happier .
For context , I get on fabulously with other members of DH family including his parents and grandparents.
DH is well aware of my feelings and I've told him numerous times to ensure he facilitates contact with his niece (it was all done by me previously). He hasn't.
Yesterday was his niece's birthday. I've not seen DH's sister and her family for quite a while .
This morning I've received an email from DH sister asking why I forgot niece's birthday and says she was very upset (hard to believe as DH barely knows her ).
The email goes on to say how I am causing a rift in the family , how I make no effort with them and how it's impacting on the niece .
There was no mention of DH (her brother!) it was all my wrong doing.
It signs off with "please don't try to pass the buck on to (DH) - you know what men are like for dealing with these things!"

DH is at work and I've text him asking if he sent a gift for neice - his reply :
"Oops I forgot - can you order something from Amazon?"
WIBU unreasonable to tell them both to get lost ?!
I thought I'd resolved the issue of everything being my fault when I went NC.
