My OH and his siblings were brought up by his gran and other close relatives. Long story short OH did not share the same views as gran and relatives on certain family issues so OH did not get along with them. He just about talks to his sister for the sake of her kids as he adores them. Anyway OH gran died recently, when told by his sister he showed no emotition and couldn't care less. I have messaged sil to offer condolences however she has been ignoring me for a few weeks now. Ive called and messaged and she's checked the messages but not botherd to reply. We had a really good relationship before and would talk every few days like sisters but dont understand why she is annoyed at me. My perception of her has totally changed now. Am i being unreasonable being annoyed at her, i know shes going through a breavement but i havent done anything wrong to her.
