My fucking family 
A few weeks ago I got a message on Instagram from my brother's ex-wife. Not spoken to her since they divorced (they live away so really barely knew her) and it was a message of condolence for my grandad passing away.
This was news to me - my grandad is my only local family, I see him twice a week, he is 84 and in good health and we're very close. After feeling the blood rush out my body, I rang my mum abroad where she lives, I didn't dare call grandad's house in case he didn't answer. I asked if he died and she said "I don't think so" 🙄
So she rang my brother whilst on the phone to me. Apparently, he had their little boy that day, as he does EOW, and a female colleague called him to say that she was feeling down and depressed and could he come over no doubt for a shag. DBro rang his ex and simply said there was an emergency and he needed to bring their son back. She said no as she has plans with her partner. DBro was apparently so incensed at this 'unreasonableness' that he lied and said that the emergency was that grandad had died. She apologised, said of course you can bring him back, and hence the message to me.
I'm obviously furious and think it's a disgusting lie to tell. Not to mention when grandad does die, what will he tell her when he needs to come away for the actual funeral and maybe miss a visit from his son?
To make it worse, my mum defended his actions, but he can do no wrong and apparently "he wouldn't have to lie if his ex wasn't so difficult"
she hates women BTW.
Anyway, fast forward a few weeks. Grandad has an Instagram account, mainly to keep up with the family, and I like to put photos of the kids on (I'm not that hot on social media but it seems to be a simple way to share pictures with him). I often put pictures of him and the kids on as he gets them saved and printed out and put into frames. I've done this this weekend when we've seen him.
I've been asked by Mum to take them down as ex-SIL now follows me and she'll realise he's not dead!
AIBU to say it's not my lie, not my problem, and I'll post what I like?
