To wonder if he’s hiding something?

[groovychick123]

I’ve been seeing a man since February but I have known him for a few years. We both split from our ex partners around the same time (by genuine coincidence) over Christmas.
Everything has been going well, we’ve had lots of lovely dates together, spend what time we can together. He’s said he thinks I’m his “soulmate” which I thought was a bit forward but other than that he’s funny, caring and I thought we were happy.
We’d had a few drinks in a bar the other night and I posted a photo of us to social media . I don’t really post on mine that much or care about likes but for context it got around 70 likes and lots of “I hope this is what I think it is” “happy for you” type comments.
as soon as I posted it, he went very quiet and the atmosphere changed. He said he was worried it would upset his ex with it being so soon? (What about my ex, we have a DC together!) and he hates SM. He took me home in more or less silence and that was the end of what had been a good night. I don’t think he’s seeing the ex as I know his mum and I’ve seen she’s gone back to London where she was from.

what do you think?

Ask him about it. There's something else going on here.

Why did he tell you it was ok to post in the first place? Why would he worry about his ex seeing it?

I would wonder if he's trying to hide this from someone too. It really makes no sense that he would be ok with you uploading it then get mad. But when you tagged him, he became visible.

That said, he's love bombing you. Soulmate after a few weeks of dating, come on now.

the decision to ‘slow down’ is possibly out of your hands now that
you have attempted to broadcast your relationship to the world

even Rosamund Pike was dumped when she posted a hot tub picture
of her and her intended and sent to all friends, he was horrified and ended things
a week before the wedding

you misled him into thinking this picture would be on your page,
now it is out there
you should remove or hide it at least

forgot to say, what he is hiding is his irritation

love this economical response

or all three

It’s only been 3 months
He’s split up from a presumably long term partner
You shouldn’t have posted/tagged without asking
He shouldn’t have gone sullen

Ask him with all the detail you've given here. Ask him what's wrong when he sat next to you and okayed the post, and see what he says.

Also, the soulmate comment is so cringe. And hardly a soulmate if he can’t talk to you about a preference and instead goes into a sulk! I’d get rid asap.

Posting on your profile is very different to tagging him and telling everyone he knows. That’s going to prompt questions he’s probably not ready for after such a short time. I’m not surprised he didn’t consent to that and felt you massively overstepped.
I have approvals on so I can check/authorise it when anyone tags me. I think he needs that too.
