I don't have a great relationship with my MIL. I find her very difficult in many ways, particularly what I consider her rude and aggressive conversation style and her inability to see any point of view other than her own. She will quite often tell me that something I've said is "absolute rubbish" and if you dare to disagree with her she gets very aggressive/ defensive. She also bears grudges and will hold the smallest thing against you for ages.
We don't see her all that often so to keep her in the loop I send her photos of what our family has been up to. I have just found out she's been posting these on her Facebook account. I am not happy about this. I know she doesn't mean any harm, but I am very careful about what I put on the internet, and hardly put any personal things up. If I wanted these pictures on the internet I'd put them on my own page!
How can I get her to stop without provoking a showdown? If she won't stop I will stop sending her the pictures, but it would be better if she didn't have to miss out.
