Was I being unreasonable posting about this on FB?

He’s scared that people will see it and think he’s a dick. Block him on all social media and ignore him.

What a cheek he has, happy to carry on an affair yet blustering when you post on FB!

Well done to you! That’s a great achievement.

Good for you - I can see why you are proud. It seems your ex is embarrassed by your post as it makes him look bad. Oh dear.

wow well done OP for buying him out! I can imagine it wasn’t easy with 4 kids. If you were my friend I would definitely congratulate you on FB. It’s much bigger achievement than visiting a place which most of FB posts are about.
I agree that any posts about ex should be worded carefully considering children but it seems they are not upset and know all of it anyway due to their age.

Hope you’ll find who send him your post and delete them. I wouldn’t delete the post and I would screenshot and methodically save everything and wouldn’t engage further with him.

OP post what you like, by deactivating your FB you are continuing to let him control you!

Yes it is. And as OP said her children are well aware of the situation, supportive and happy about it.
Her husband was controlling and obviously still wants to be.

I would care if it was my friend! But that's what having good friends means. What a nasty reply.

I absolutely loathe that some posters on here have agreed with your prick of an ex. Even suggesting it’s unwise is bad enough. It’s absolutely none of his business. He’s still trying to emotionally control you. Write what you want on your page. Well done to you. Never be afraid to be yourself and why should you not be congratulated for your achievement. And never let him know anything about your life from here on. He has zero say in anything. Get the financial order completed. Be done with that utter wanker and ignore the spineless mumsnetters that are facilitating male oppression. I agree with not putting everything on FB but it’s your choice as an adult what you post. As long as it’s not defamatory/bullying/racist etc. and this wasn’t. You stand up straight and be proud.

Not suggesting this for anyone else’s sake but the OP’s. Surely people can share good news with friends/family without the need to make public posts that will inevitably be seen by people they wouldn’t want to see them?

And given the OP wants to post it to her friends and family on FB my suggestion is that she clears out the shit-stirring ones is also for her sake.

Clearing out the people she wouldn't want to see them, because they'll shit stir with her threatening ex, will be useful going forward for anything she post.

Ok, that makes a difference and his reaction is even more disproportionate.

Sort your settings and then be a sleuth and find out who the spy is. A bit like what Coleen Rooney did.

Did you miss that they split up 8 YEARS ago?

I read it as though op wrote something like, "this will now be a good day instead of the anniversary of the worst day of my life" (discovery of an affair). I personally wouldn't have done that with children involved.
It is something to celebrate though.

Absolute do not treat this as a lesson in what to post.

Treat it as a lesson that you need to cull a person or two from your FB...

You wouldn't care about a friend in this scenario? How sad for you.

I’d be interested if a friend had been in this situation. But then I have friends…

Well done for doing this - and for buying the wanker out! Treat it as a lesson in being more careful about what you post in future, ignore the idiot and enjoy your freedom 🥂

Oh and don’t get into a slinging match on social media as someone has suggested - I can’t think of anything less dignified.

I find this sort of post about social media odd. I mean there are degrees of caring. If I wasn't mildly interested in people's news I would unfollow them on Facebook rather than blame them for posting it, assuming they don't bombard stuff.

@Shnuzzbucket it isn't his business but it's causing drama. Facebook drama is all unnecessary. I would take it down and get on with my life. OP is not unreasonable to leave it up but I just wouldn't want the hassle.

It's poking a bear.

Tell him to go fuck himself. His years of pissing over anything good in your life are over, and he can take his bitterness and fury and shove them up his arse because you have moved on, and maybe he needs to.

Well done for that. No chance you should be expected to tolerate him threatening you

Just don't respond to the messages
Agree

and take the post down.
Disagree
Her Facebook, her post. None of his beeswax.

I'd say the thing to sort is working out who sent him the screenshot and removing them from FB.

He's got no right to dictate what you post. And sorting yourself post separation is an achievement so well done! And don't let his threats taint it.

I'd be keeping his messages and once your divorce is all sorted I'd be telling him that any future threats (and threatening to "sort it" absolutely is threatening!) will be reported and you'll go down legal routes with him.
