Me [25M] with my gf (25) that social media question again...

Well, here it is again. That question that everybody asks....is it normal that their SO does not show them off at ALL on social media?

A little background information, my SO and I have been together for 4 years (separated for 1 year in that time span). And she has never posted a single picture of myself and her, never changed her relationship status, etc etc...we have had an adult conversation about this as well.

Now, I'm no social media enthusiast either but I only say this because in the past I have caught her being a bit "shady" on social media by having guys message her, and her saying she is single, or otherwise being a bit too flirty and possibly seeming single on social media. Most of the pictures she posts on her accounts are at events we are at together, yet no mention of me. I'm not on social media all too much, but I am just weary because of past events and what I've caught her doing in the past.

And back to it again, but in the year we were separated, she would post pictures of herself and other guy friends she dated for short amounts of time, and she also posts pictures of her and her guy friends. Now I am not a bad looking guy by any means, but could she possibly be hiding me and waiting for something better? Sorry if this sounds a bit immature for our age, but I just feel relationships have definitely changed with technology and social media, etc.

I see other couples post pictures with each other all the time, is what I'm asking too much? A picture of two of us together? Btw I do post pictures of us together on the few pictures that I do have on my accounts.

TL:dr gf does not show me off on social media, I have caught her being a bit shady on the internet before, am I asking too much? She has pictures of past relationships and herself as well as her other guy friends and herself but none of us two.
