<human>: I met my gf at work 18 months ago. She worked as an intern and i started giving her rides home. We started dating and now have a great relationship.

 I know how the man of her dreams should look and act (we used to talk a lot about it in the car after work, before we started dating). I dont fit the looks or act like the man she dreamed about. She hasn't mentioned this and i feel like she loves me for being me.  

9 months ago another intern(B) started. B is a part time model and lead singer in a semi famous band. He fits the looks and the act of my gf's dream. She started talking alot about B. (B did this at work today; B is so cool. ect.) After a week, i told her that i wasnt interreeset in hearing about B every day. She apologized and stopped talking about him.

Their internships ended and they started school together. She doesnt talk about him anymore, but she shows interest on Instragram. She likes nine out of ten pictures he posts. She never comments on them. She follows 150 people on instagram (fashion and her girlfriends plus some other guys from school) and rarely likes other pictures. The amount of instagram attention she gives B is very far from normal instagram activity for her.

I feel so jealous about her liking his pictures on Instagram, and i really wants to know why she does it? At the same time I know my jealousy is stupid and I need to stop Instagram stalking her likes, but I don't know how.

Provide a brief overview of the text.
