I know this will be quite divided, so am prepared for the truth.
My DH fell out with his mum a few years ago, for the last year he has been getting back to normal and things are slowly repairing after a really horrible time. At the time his sister took their mums side and we didn't speak to her again, dh has never liked or got on with her (she has never liked him either) so it wasn't a big fall out with his sister or a love loss as such.
Anyway, his sister has recently become pregnant we have two children and know far to well how difficult first babies are, I decided it would be good to repair things and make sure she knows if she needs any help it is here. So I sent her a message congratulating her on her pregnancy, I apolgised for our part in the fall out and expressed it would be great for the cousins to have a relationship and I would love it if we could get together for a coffee and a chat.
I never received a reply, however MIL told me she has the message. then last week my mil said to DH that his sister would like to speak to him, he isn't in the slightest bit interested and cannot understand why she would want to speak with him. He also told mil it is rude of her to blank me and it seems like a power play.
So aibu expecting her to reply to me? Even if it just acknowledged that she has the message. If she had messaged me I know I would reply.
