For this small matter to be a deal breaker?

[Ifiwerea]

My boyfriend of 6 months refuses to follow me on social media. I follow him. His profile is public (and so is mine). He says he doesn’t like to follow the women he’s dating.

He has also put lots of photos from our travels online, but never with me in them.

He doesn’t seem to be keeping me a secret in the real world. I’ve met all his friends and family.

I just spotted him liking the photo of a very attractive woman that I believe is an ex of his, a few days ago. She has also been liking his posts.

This feels enormous to me. Perhaps it shouldn’t and perhaps I’m being very immature and insecure, but to like a pretty photo of another woman that he clearly knows well, while he won’t even follow me, let alone post a photo with me or like any of my photos, feels an absolute deal breaker, for reasons I can’t really articulate.

Am in being utterly ridiculous to bring this up?

I've no idea why you're getting such a hard time OP, YADNBU. It would be different if he didn't like or doesn't use social media but given he does it's such a small/easy act of public acknowledgement of the relationship and it's so clearly important to you that it doesn't matter if you're being rageingly UR in a way, a loving and committed boyfriend would surely just do it anyway. Like those women that make a big deal of insisting their boyfriend bring them chocolate when they're on their period, myself I don't see/get it but it's a small loving favour, why wouldn't you? It's not even like you're asking him to explicitly add a relationship status like the bad old days of Facebook, just hit follow and like a picture or two, you might do that with a total stranger or random acquaintance. And it makes it even more sus that he's liking his ex's pictures knowing you'll see it, being cynical it's almost like he's making a point that he's a free agent. If you've tried talking to him already and there are other problems in the relationship your gut might be right to tell you it's time to call it quits?

I think you have bigger fish to try. You are in your forties and obsessing about social media like a teenager. Grow up a thicker skin.

So many comments that completely fail to understand the principle over the detail. I am not an avid social media user and I am happily married but even I can see this is concerning in terms of the principle.
