I know most of the replies will be ‘how old are you, 12?! Why do you care?’ etc but I’m wondering if other people feel similar?
As an example, SIL never likes/ comments/ responds to anything I post on FB. I don’t post that much, once every few weeks and (in normal times anyway) it’s mostly photos of days/ nights out with friends/ pictures of my dogs/ scenic walks etc. Occasionally it might be the odd status but that’s rare.
SIL posts most days, mostly pictures of my niece and nephew or something related to my niece and nephew like how their parents evening went etc. I usually like her posts as I love my niece and nephew so why not?
My mum made a comment a couple of weeks ago that she’s noticed SIL never ‘likes’ anything I put on FB. I joked that she’s probably unfollowed me (it’s probably true but why I don’t know as I post nothing offensive) my mum said she thought it was quite bad as she likes all our other family members posts and is all over them all the time even though she’s only met them a few times.
Yesterday I posted some ‘life news’ obviously she hasn’t liked/ interacted with it at all. Before when this has happened, the next time I see her she’ll say something like ‘oh congrats on the new job, I saw it on FB.’ So she clearly does see things. Obviously I’m not seeing her atm so she hasn’t had a chance to tell me she’s seen my news on FB (just letting me know that she DOES see my stuff) 
She’s posted tonight a picture of her and my niece and nephew, I went to click ‘like’ and then thought, no, I’m not going to give it my usual ‘like’ because as petty as it sounds, I’m starting to think why the hell should I. She takes zero interest in my life, not just on FB but in general, she makes it clear she doesn’t really like me yet puts on a performance in front of my other family members and I’m just a bit sick of it tbh.
I feel bad as it’s not my niece and nephew’s fault but ultimately, I feel like a bit of a prat constantly interacting with someone’s FB who completely ignores mine.
People always say ‘FB isn’t real life’ but sometimes it can be reflective of it. I’ve had conversations with friends who have said they’ve deliberately ignored certain people’s SM posts, people do do it.
Do you like people’s posts that never interact with yours, or have you done similar?
