Most guys want to believe that their girlfriend is a princess. You want to believe she's loyal, true and kind, and above all completely honest. Just because she isn't lying to you doesn't mean she isn't cheating. This list will show you how your girlfriend could be keeping you wrapped around her little finger while she sleeps around. Don't get taken for a ride and read this article to make sure you're not just a hook-up.

1) She won't call you her boyfriend. If you haven't had the boyfriend/girlfriend talk yet, she can sleep around and not be cheating. It's definitely not fair, but if you havent said the words, she can still be dating on the side.

2) You guys haven't talked about monogamy. Even if she does call you her boyfriend, you might not be the only one. It's modern times and a lot of girls are completely ok with open relationships. This means both of you have the right to sleep around. She might even think you're dating around and sleeping with other women. Before you can be sure she's not sleeping with anyone else, you need to be very clear about what you want and tell her what is and isn't ok with you or she won't think there's anything wrong with having three or more 'boyfriends'.

3) She's hooked up with her girlfriends. There are so many guys out there that think that if a girl sleeps with another girl, it's not cheating. If your girl is bisexual, she could be hooking up with her girlfriends when they go out and not think it's cheating. If you don't want her falling for a friend, you need to make sure that you're clear about what's ok with you and what isn't.

4) She's still really good friends with an ex. This is just a bad situation all around. It's ok to be friends with an ex, but if they're flirting all the time or you feel tension whenever they're around, there's probably some unfinished business involved. Don't be the rebound and make sure she isn't cheating on you with her ex by talking to her about it. If she gets weird when you bring up the subject or really defensive, you have a problem on your hands.

5) She gets gifts from other guys. Your girl won't accept gifts from other guys if she's faithful to you. Every girl knows that unless a guy is an old time friend or family, an expensive gift just means they want to get some. If your girl is accepting expensive things from a guy, he's trying to get in her pants, or already has. Keep your eyes out for big buys like perfume, personalized gifts, dinners out, purses, cell phones, and some guys will even go as far as plane tickets or a car.

Don't get caught up in a girl that won't be faithful to you. By following these easy guidelines you'll know right away if your girlfriend is sleeping around.
