Am i the one who should appologise .....

I understand why her behaviour can be upsetting to you. It appears she easily finds faults and get angry for the slightest reasons but in this pregnancy announcement/Facebook instance, YABU i am afraid.

So I’m going to go out on a whim here and say that this is much bigger than just this incident.
I think you are feeling upset with her because of a few small incidents and things have piled up for you and now this incident is sending you over the edge.
I think the incident itself is “pathetic” and meaningless. She already knew. What’s the point of her liking it? Commenting? For other people to see that she did? Social media expectations can ruin relationship and mean nothing at all. What matters is your relationship in real life.

I am a strong believer that ego has no place in relationships that matter, so if I were you I’d pick up the phone or go see her and tell her why you are really upset and I doubt this post is the reason.

do you feel like she loves your siblings more? Do you need more attention? What is it that you want/ need for you to feel secure in your relationship with her? Voice it.

I think your mum is being a little petty but if she was thrilled for you when you told her then I’d let it go. My DP was huffy when I didn’t wish him a happy birthday on Facebook when I had done it in person that morning. It’s all a bit pathetic to be honest

Since this is obviously a theme for her with not just you but everyone, I'd back off and just stop including her or making any effort. Leave her to stew and focus on having a happy little family of your own.

This ^^

As others have said, your mum is being manipulative and attention seeking. Ignore it. If she wants to be all funny, let her, she will be the one missing out due to lack of contact. If you submit and apologise to her for this ridiculous and incorrect perceived slight you will be enabling her to do this everytime she wants to manipulate you in the future.

Sorry, what? I think she is saying that you should have tagged her if she was expected to comment. How else how would she know she’d not done what you wanted? She posted photos of the graduation because there were photos to post! Did she post photos the day you sister found out she was going to uni? And even if she did, is she not allowed to have an off day where she doesn’t manage to keep up with all of these acknowledgments?

If she would want you to write HB on her wall then that’s her problem and I would politely rise above it.

Hi, just so you’re not thinking you’re bonkers for being upset over this. People here clearly have good boundaries with Facebook, but my mum’s the same. If I don’t like something she posts it makes her paranoid and she will ask me about it later. My mum, bless her, has made up her own Facebook etiquette and will delete something if it’s not had enough likes. As your mum sounds similar over fb then she’s clearly making a point and being petty. Try to rise above it and ultimately you’ve got to decide if putting up with the constant eggshells and pettiness is worth it so that you can have a relationship with her. My MIL can be like this, but more Machiavellian and my wife has tried NC but in the end she’s decided she’d rather put up with her mum’s nastiness at times to so she can have some kind of a relationship over having none at all

YABU. Why would she need to comment on Facebook when she’s already commented in person, in real life where it actually matters

She does however sound an absolute nightmare in general, my own mum is the exact same and it’s draining but for this particular scenario, you’re being petty

I must be a really horrible mother then because I don't comment on my kids stuff when they've told me in person - it seems weird. But I do post happy birthday on their wall even though I do it in person and with an actual card.
So what if she posted photos of your sister's graduation - what did you want her to do post your scan photos?
And yes if you want someone to come to your son's party you send them an invite - it's common courtesy!

How was your Mums reaction when you told her in person you were pregnant? Was she happy & excited for you & showed it? If so does it really mater if she didn't comment on your FB post? Try not to let her get to you at such an exciting time. You've let things go in the past, try & let this go too as she'll not change & if you want her in your life you'll have to accept that's how she is & it's not going away. Make sure you tag her in the post once baby arrives & you introduce them to your FB friends. Give her nothing to come at you for but make sure she knows you're only doing it to please her so it's ammo for you in future if she says you don't include her in anything.

with all the other crap she pulls the one that bothers you most is she didn't like your facebook post. Alrighty.....

Like mother like daughter, I suppose. You are both are ridiculous- you for posting a pregnancy announcement on social media for your mother/family to find out. And she for acting like a victim.

I stopped reading after a few sentences. That is all that was needed

frankly, it seems you like drama and attention seeking on social media.

she’s your mother, you should have called her. Everything else following that is your drama you created and just add to

frankly, she should just unfollow you so that she doesn’t see what you post nor people’s comments to unless she specifically goes to look. Could be a way of avoiding the drama. Perhaps she already has hence not seeing your post.

No she doesn't need to comment, she's known for ages , presumably fb more to tell friends

Secondly it seems you have an online life and a parallel real life relationship with your Mum with different understandings of unwritten rules, expectations and etiquette - perhaps these need clarifying so you don’t annoy each other - the FB issue should be just a simple conversation with your Mum (but not helpful when clearly she’s lying)

The FB disagreement is not the issue here… the problem is your Mum using opportunities to ‘have a go’ - it is clear she is controlling and manipulative and things obviously get tense when you try and find some independence or set boundaries. You seem to generally have (or want) a nice relationship but there is a ‘control’ dynamic going on that needs addressing.

She’s your mother so , after your husband being told she should have been next not on some impersonal Facebook site.
YABU and should apologise to her.

Sorry but u should know that this is about her grandchild. She’s been snubbed by not being included in the FB post.
Before I get attacked, yes I’m being sarcastic. But this is also what I had to deal with from my mother.
Sorry if I’m the one to tell u but if she’s like mine, u will never get an apology nor explanation (unless it paints her as the victim in all this). She is the main character. If anyone tells her something she doesn’t want to hear, then it’s an attack & these people must be punished. In her eyes the worst punishment she can give is silence as who wouldn’t want to be part of her inner circle? Enjoy the peace.

I believe you OP, but if you know what she's like, why didn't you tag her?

Either play along or completely cut off the social media part of it.

Fuck me get some real problems.

The apple doesn't fall far from the tree does it 🙄

Omg this is why I'm no longer on FB. So much drama and unnecessary headache.

I agree.
