10. They don't pick up the phone
While men feel good as they manage to take the girls' phone number, the girls often give them a fake number or don't pick up the call.

9. Use men for free drinks
Some women go out never planning to spend any of their own money on drinks at the bar or club. Instead, they count on their feminine wiles to convince guys to shell out for their libations. While some of them might begin to get to know him, the cruel and heartless ones will take that drink, flirt a little and move on.

8. Use men as placeholders
If she is a decent person, she'll just get it over with and dump the boy, but if she's cruel, she'll hold on to him for a while until somebody new comes along. These girls don't like to be alone and without a relationship, so instead of putting you out of your misery and ending it, she'll string you along until she meets someone to replace you.

7. Emotionally manipulate men
Men don't like to see women cry and some cruel women take advantage of the fact and use it to get what they want. A few tears would make men do anything to get it to stop.

6. Use physical violence
While men hitting girls are often termed nasty, some cruel women feel it's perfectly acceptable to hit their boyfriends, as he would never hit her back. This type of woman feels like she can inflict any kind physical pain on him without fear of repercussion.

5. Criticize their men in public
Cruel women criticize and humiliate their men in public places. They often poke fun at her man or even soundly debase him.

4. They don't disclose their relationship status
It's certainly not the worst thing a woman could do to a man, but it is annoying when she's already in a relationship and lets you assume that she's available so that she can enjoy the man's flirtation and flattery.

3. They withhold sex
This is a time-tested, and frequently used, cruel thing for women to do to men. For most men, sex is as important as breathing, so withholding it in order to get something she wants or simply to punish her man for his transgressions is a pretty awful thing to do, even if it is effective.

2. They test their men
You're all ready to go for a night out with your friends, when your girlfriend calls and asks you to change your plans to be with her instead. She doesn't have any particular reason; she just wants to see you. She knows that you had plans to meet up with the guys, but if you really loved her, you'd come over to her place instead. If her request comes with an "if you really loved me," then it's a test. If you choose anything other than immediately rushing to her side, you're going to fail. This kind of testing in a relationship is indeed cruel and petty.

1. They flirt to inspire jealousy
Maybe she's feeling underappreciated, maybe you've just had a big fight or maybe she just enjoys the tortured look on your face. For whatever reason, girls who flirt obviously with other guys in front of their boyfriends are immature and manipulative.
