if you mean "How do you know if your girlfriend still likes YOU"...Then you have to see if she spends time with you. Or does she make excuses not to spend time with you? Does she kiss you passionately? Or is it a quick goodbye kiss? You can tell by the way the look at you, too. If they look at you like you are the only one in the room, your good! But if she isn't paying much attention to you, then maybe its time to move on.

Check if he still keeps her old presents
If he has moved on and has a new girlfriend it is time for you to realize it is over and move on as well.
Don't worry about that, the important thing does your girlfriend like you.
If he likes you, then he won't have the other girlfriend anymore.
If you don't know if your girlfriend likes you then you need to get to know each other better because she should like you before you become girlfriend and boyfriend.....
make your girlfriend jealous
As long as he has a girlfriend, say nothing.
then he must be cheating on you if he has a girlfriend? i mean if he likes you and has a gf then he must be cheating and wanting you?
HELLO!?! Do you know nothing? It's because she still likes you, or has feelings for you. Open your eyes. If you can't do that, then you don't deserve her.
