well you can reas their bidy language or just ask them. but it all depends.\n\nThe problem is that body language is not always a safe way to find this out whereas by asking is just one simple step as the worst possible answer could be NO. There are some girls who can imitate the body language of an interested girl, but they are not interested in you. They will only play with your heart and/or use you.\n\nThese are some techniques to detect these types of "users" and that help to protect you from being used:\n\n1. First check out if she will give you her phone number, and if this is her true number! If she won't give you her number or it is a false one, forget her!\n\n2. Check out if she will go on a date with you. If she is "too busy" all the time or something like that and it is impossible to get a date with her, then she is not interested.\n\n3. If she is asking you to buy her a drink the first time you flirt with her, then alarms should go off in you head. Don't allow her to use you this way!\n\n4. If you are on a date with her do something where you don't need to spend too much money and don't bring her a present on the first date. You want her to love you as a person and not to love your presents or the fact that you pay for everything. Try to keep the temptation of using you as low as possible.\n\n5. After the first (or maybe the second) date tell her something like "Well, I really enjoyed...." and so on and "Maybe we can do this again next time. You can call me..." It is important to tell HER to call YOU because she will only call you if she is interested.\n\n6. Analyze if she only wants do things that make her happy. For example, if she is calling you only if she wants to have someone to repair her car or something like that, but never calls you for a normal date, then think about it...\n\n7. If you find out that she has a boyfriend or if she even tells you that... FORGET HER! She may pretend that she is interested in you and that she might leave her boyfriend for you, but she will NEVER DO IT!!!\n\nTry to use the methods from the above and ask yourself always if the ratio of giving and taking is 50 to 50. If you realize that it is not, then stop giving and see if she still wants to continue the relationship (or the flirt etc.). And DON'T get blind because of your feelings and/or her body language. Even a "user" may have a sexy smile..... ;-)\n\nanyway hope this helps.
