Just because your boyfriend thinks the new girl is pretty, it does not mean he’s going to dump you. It means he’s a normal guy, who notices girls and talks to his friends about it. It doesn’t mean he thinks she’s prettier than you or that he wants to go out with her. Don’t make more out of it than what it is. Be honest—don’t you notice when a new guy is cute? That doesn’t mean you like your BF less. However, if he obsesses over other girls or shamelessly flirts, you might want to consider dumping him!
