My girlfriend doesn’t post about me on Facebook, I’m confused

Dear Aunty Lisa
I have been in a relationship for over a year now.
I have come to love this girl very much and all I do is show her to my family and the world at large because I am proud of her.
On her side, she keeps on telling me that she loves me very much and she will do anything for me. But my girlfriend has never posted a picture of me on Facebook or any other media platform to show to her friends and family that she is in a relationship with me.
Is she really proud of me or perhaps there’s another guy she’s seeing?
I feel I am blinded to this relationship. What should I do?
