AIBU to cut this person out of my life? Competitive or manipulative mate

[Maximumdelusionstrawberry]

I'm 29, in 3rd trimester with 1st baby.
'Friend' is 35, in 2nd trimester with 1st baby.

We've been friends for years but a couple years ago she started being super competitive. A 'topper' they call them right? A lot of it was on social media, i would post a photo of myself and DH on holiday, she would have to go to the same place and do the same things but MORE photos and MORE intensely joyful captions. I got my first tattoo, and a couple weeks later she has one. I got a second tattoo, se got two more massive ones. Same with things I was into, I really like running, and used to do races etc... like 1/2 marathons. Runnin helped me through some dark emotional patches in my life, and it's really something I genuinely love. She used to make fun of my running, then i encouraged her to try when things in her life got a bit tough. I helped her with advice, kit, moral support. She started to follow my mapmyrun and comment about how many kms I'd done, and post photos and videos of herself running on FB/IG.
Now it's babies... what gender, what prep, weight gain, what have you bought, what's the nursery like. I've been quite guarded about the whole pregnancy after a m/c last year, but she follows and comments on all my social media. This is just one thing I want to protect and don't want her to ridicule/compete over. Maybe I'm being a bit of a grumpy preggo but I'm kind of just SO OVER it all.
Contextually: she's a really good friend and other than all this i enjoy having her in my life
Has anyone dealt with this? Have you had a positive outcome? I feel like I'm overreacting but i just want to tell her to B**ger off!!

I can't actually see what she's done wrong. Annoying in the way she has copied you, yes but nothing really that bad

This must be massively annoying but if she only knows what you put on social media then just don't out stuff on social media. Announce the birth personally and only put it on Facebook etc. when you are ready to.

It sounds like she thinks highly of you and you opinion and tastes but would do my head in too.

What happens if you keep personal stuff personal? Limited info is the way to go.

I don't see it as her being 'manipulative' unless there is more to it. It just sounds a bit annoying! I have a family member who is similar - I actually don't tell them ideas as they will end up doing them before me. But DH thinks it's more because they aren't creative themselves with ideas, and they like to 'belong'

Genuine question....why do you put stuff of social media if you don't want people to like or comment on it? Or take it negatively when they do?
And why are you annoyed that she got into running and commented on your runs/posted her runs on social media when it was you that encouraged her to take it up in the first place?

Givemestrengthorgin: That's a good question. It's not that I don't like comments and sharing things on social media. I love it when I see my friends are doing fun/exciting things and love to encourage/comment n a positive way. I may not have explained this properly, but I always feel like to comments are negative in a way- either making sure I'm aware that I've run less this week than the next, or letting me know that she doesn't approve of my choice of x y z for baby. Social media for me has been a way to follow my friend's lives in a positive way, and I love doing that. I've hardly post anything about my pregnancy, as that's something I keep very quiet, but sharing photos of food, pets, travel is something I've always enjoyed... Maybe a generational/personal thing!

Op I think it's probably that you're finding it hard because you're pregnant, but I hear you.
There is a way to share things on fb but hide it from specific people, it's in the privacy option for each individual post. On insta you can hide your stories from her but not your posts.

Honestly it sounds like you are someone she looks up to and the copying is more about admiring you and feeling safer in her choices as you've already done it.
Unless she develops a mean streak about her imitation I'd just be low key and not share anything you don't want her to adopt.

MoistCantaloupe - You're right, I left out lots of other stuff when I was writing the post. She also will also do this thing where she will see something I've posted, or hear something about me, and in a group of friends, speak negatively about said thing. It sounds really coincidental, but it's so specific I've realised it must be directed at me. For example, I'm choosing to cloth nappy, and I've posted questions about it on social media asking for suggestions etc... from my mummy friends. Next time I see her in a group of people, she is loudly telling them how bad cloth nappies are for babies, environment, how much work, how they're for hippies bla blah. Sounds petty but it's constant and it does get me down...mainly cause I don't understand why she is doing it?

Lizardtoes - I think you're right. I'm a little intolerant this days, and I don't want to act out and hurt her feelings/spoil the friendship just cause I'm hormonal :/

That's actually an amazing idea, thanks! Just hidden my story from her!
