[ Friends ] Open question: She makes me soo angry ?????

I'm a 24 year old guy, I fell in love with this girl Nicole. We started to go out and everything went well between us. But in the end, she ended things between us. She told me that she did not have a pharmacy with me. 3 days after our break it was her birthday. So I bought her flowers. She told my best friend that I'm a stalker. This girl also has a 4 year old son. She told me that my life is not crushed as a role model for her child. She was in college to become a nurse. I found out today that she's dating a new guy, and she even dropped out of college to be with that guy. This guy has no job, NOTHING. It makes me angry how she tells me that my life has not been stabbed, but I have at least two jobs. This situation makes me sooooo mad, can I please have some advice ?????? ,
