This may be a little long and ranty. But it needs to be.
I left DS's father in 2009, following four years of abuse. As a result of death threats, and feeling I had a lack of support, I moved pretty much cross country, but have tried to keep relations with the ex's parents civil. As a result, they've seen DS once a year for the past three years; twice, they came down for a weekend, and saw DS for about three hours each time. Last year, we visited them for an extended weekend. We were due to visit them again this year.
We had a letter come through over the weekend, and I've been silently fuming since. They've informed us, in said letter, that DS's grandfather has cancer (they've known since January, but waited until March to inform us) and have informed us, that because DS's GF will be undergoing chemo, they won't be seeing DS this year, at all. (They're still seeing their other grandchildren who live closer) They don't phone to see how DS is, yet they expect a card and cheque for his birthday and Christmas to be sufficient to let DS know they're thinking of him. I've stopped phoning them, as I was tired of being the one to put all the legwork in. I'll probably get flamed for that by a couple of users, but it became apparent whilst I was revising for exams, resits and doing assignments, that they didn't phone once during a two month period. I gave it another month. Still nothing. I actually feel hurt on DS's behalf; it feels like he's been reduced to nothing more than a name on a Christmas card and birthday card list. AIBU? :(
