Why does my boyfriend always have a picture of another girl as his phone screen saver? He knows I don't like it

Anonymous
I'm dating this guy he is older than me, he has a picture of this girl he knows on his screen saver phone. It's always her, never pictures of me, he does not even have pictures of me in his phone. He knows that I don't like it but keeps it there. He says the girl is like a daughter to him..BUT SHE IS AROUND THE SAME AGE AS ME! They never hangout. The only reason why he knows her is because he used to drop her off at the movies and the mall because she is my cousin's best friend. He compares me to her sometimes and says "well she does it" "she does it that way" It makes me so mad, but he does not care. What do I do? That is not his daughter, they do not have a bond. But when she wants him to drop her off, or buy her something I guarantee you he will get it or do it for her. But it makes me so mad...seriously! HER PICTURE IS ALWAYS ON HIS SCREEN SAVER WHEN HE OPENS HIS PHONE. HER HEAD IS RIGHT THERE!. OMG WHAT DO I DO?

He said he knew her since she was 14 and I'm just jealous. Am I wrong? He is a lot older than me.
