Bare with me this may be slightly long!
I have been married to my husband for 11 years. He is one of eight. He has 4 sisters 1 older and 3 younger and is one of 4 brothers. For reference we will call the older sister A and the one 2nd younger than him F. All siblings uses to be very close. However, in the last few years arguments have happened between the sisters and A has ended up being oscrasized by the siblings. She has a good relationship with my husband but he had always stayed neutral and tried to stay out of their disagreements. In the last few years this has meant she hasht been invited to any family events, except our home. F is getting married and the entire family is invited except A and her family. Her children seemed upset that they too couldnt go. My husband asked for F to invite A and she agreed. She however, rung her 11 year old who clearly wasnt comfortable speaking to her and asked her to tell her mum to ring her back. A did not ring back because she felt uncomfortable ringing and coaxing an invite out. Anyway neither party rung back. My husband feels F didnt really try and has now said he too wont be attending the wedding seeing as his other sister will not be attending as she hasjg had a verbal invite even. Rest of the siblings have been giving him grief for choosing A and ruining F's wedding day. F is upset that she tried but A never rung back. Am i wrong for not attending Fs wedding day or letting the kids go seeing as shes unwilling to speak to A and invite her. A has said she is totally fine with us going but it just doesnt sit right. Also to note, nothing major has happened foe A and F to dislike each other this much. Not sure now if im wrong for also not going.
