Girls like to talk, so if your girlfriend is calling or texting a lot less than she did in the beginning of the relationship then consider it a warning. If you are constantly the one making the calls or sending the texts first, it might mean she is beginning to lose interest in you. If your girlfriend is checking out or flirting with other guys in front of you, she is probably looking to get out of the relationship. If she talks about other guys more than she mentions other girls, or if she consistently compares you to other guys, it might be a sign that she's ready to end things. She could be friendly to everyone, but if it comes on suddenly, there are many examples of comments that should raise a flag:  “That guy in my math class is so smart! I bet he would be a good tutor for me!” or “I met this guy at the gym yesterday and he was lifting 150 pounds! He could’ve lifted me!” ”The new guy is kinda cute; I wonder where he’s from.” Girls will naturally get a little jealous if you flirt with or check out another girl in front of her. She may also get mad, and this could easily lead to unnecessary confrontation, or push her away.  If your girlfriend doesn’t care that you are flirting with the waitress on your date then you might want to reconsider your relationship. Try flirting with or being overly friendly to other girls on a date to see how your girlfriend reacts. Fights are bound to happen in all relationships, but if they start occurring more frequently, there might be a problem. If arguments over little things start to become big blow-outs every time, you should take some time to evaluate your relationship. She may be starting to lose interest in you romantically.
