My dh & his sister have been close over the years, despite there being a 10 year age gap. Initiating contact has been about equal til about the last few months. She hardly ever visited us though as her dh was a bit controlling & she doesn't like driving far. We only live 6 miles away, all rural!
He visits her on her birthday but it's never reciprocated, he always has to go to hers to collect card & gift for his birthday.
Her dh died just over a year ago & he's given her a lot of support. She seems almost relieved. Got herself a new man & new friends. Not judging for that but over the last few months her initiating any form of contact has been very low. It's always him making first move. It's now been 2 weeks since he last spoke to her & he's hurt, won't ring again as he's fed up of it always being one way.
She's retired & is not busy with work or children. He's had a nasty virus & so has been low anyway. Maybe she has too for all we know.
Now he's talking about boycotting her 70th birthday celebration & not asking her to his 60th later in the year.
Is he being ott, or justified? Seems sad to let a sibling relationship go when you're 60 & 70 years old
