<human>: She's the first woman I've dated that posts pics daily, usually 2-3, on social media. When we go places or to events, she will post them of us, her friends, etc. She takes them via Instagram and shares them to Facebook immediately as well. 

Here's my problem. I have noticed as of about 5 weeks ago, she stopped sharing pics of us to FB. She still posts her pics and her friends to all platforms, but the pics of me and her are limited to Instagram. There's been 7 or 8 in the past month that she didn't "share" to facebook. Also, she didn't "allow on timeline" 2 different pics I posted of us on facebook the past few weeks. I ran this by my roommate and he agreed it is weird and should be a red flag. 

Now, I feel silly even bringing this up, but I've never dealt with this type of thing before. When we first started dating she was adamant about it, and wanted me to post our pics as well to all platforms (silly and redundant IMO) but it was what she wanted so I gave it to her. She's been a model and pageant girl type her whole life, so she's obviously into pictures of herself all dressed up (high maintenance, indeed).

Side note: we are not listed as dating or together on FB.

I feel she's hiding me from somebody or something due to the sudden change in behavior, possibly downplaying our relationship. Am I cool to bring this up or is it silly/paranoid/irrational? I've always been on social networks but never took them seriously. Her and all her friends are extremely into it.

Can you provide a brief overview of the text?
<bot>: Girfriend stopped posting pics of us on facebook and it is obvious to others. I think she's hiding me or downplaying our relationship.
