To not get consent to post in AIBU?

I agree. You don’t need his permission to post on an anonymous forum predominantly of women to seek advice. If he behaved better you wouldn’t need to.
Interesting that instead of taking on board your unhappiness or concerns, his problem is his privacy? It’s unlikely to be outing unless he goes searching for it and then only he’d know.
Just anonymise more in the future. I suspect you’ll need further advice if this was his reaction.

If women had to ask consent from the people in their lives to post about them on MN then there would be an awful lot less threads on the forums.
I thought the whole idea in boards such as Relationships, AIBU and Divorce and Seperation was for posters to be able to discuss problems in their lives which often involve talking about their H, partner, boyfriend . And also both male and female relatives.
On the proviso that it is posted without identifying details it is totally unreasonable to expect to get permission to post anout someone. It would be cutting off what is a valuable source if advice and support. And sometimes the only source of help for some OP's.

So no. OP shouldn't need to ask permission to post about her H.

He has a point, if you're sharing very personally information, there is sluths or trolls that will try to out your RL info.
I believe the there is a sub reddit for slating MN and users.
Haven't seen it.

Sorry I don't agree with other PP, unless you've identified him or slandered his name etc, he has zero right to tell you what you can and can't talk about in an anonymous forum asking for advice. What if you went to an AA/NA meeting? Do you have to ask permission before you mention anything relating to him? What about good posts, do you need permission then? What about FB posts? He can't pick and choose what you need consent for. You can write about whatever you want, obviously without slander, defamation, naming etc. He's just upset because it was a negative post.

I think that now he has expressed his discomfort about you doing this, it would be unreasonable to continue posting about him without consent.

Lots of people are anxious about the security of online privacy. For ourselves, we take the small-but not-zero risk of being outed by posting on MN. But we aren't entitled to do it for other people once they have made it plain that the risk isn't one that they would take for themselves.

Also lots of people feel really upset and embarrassed about the thought of being discussed critically on a forum. If someone says 'don't do this to me' then you should stop doing it -- unless of course the person has done something really bad, like behaving abusively.

If it’s details about him and he’s asked you not to post publicly, then you should respect that. If you want to post about yourself or any effects he has on you, that’s your business.

I think that's fair enough, if he's specifically asked you not to post about him without his consent. His privacy and hacking fears are very valid.

Well i am sure women are perfectly fine with men putting their lives on the internet with no thought to privacy or it being out there identifying or not

How did he know you posted about him ?
