How to be positive that my married woman friend likes me?

Gilbert writes, "I like a married woman but I don't think she is interested. How do I find out. I just want to keep it casual, NSA. She is a really cool woman otherwise but I am afraid I will upset her if I tell her I want her."

As you said, she is not interested, but what makes you think so. Remember that many married women simply assume that no one will be interested in them (though vast majority of them are not interested because they are truly faithful). That means that you must make sure before assuming this that she is not interested and is not inclined to be persuaded either. So that you don't spoil your friendship with her and make a fool of yourself, please do not say anything directly or make a move. You have to watch her moves to see if she sees you as a "brother" or she gives out seductive signals.

Another way to test is to ask her hypothetical questions. For instance, if you are watching television and see Megan Fox, you could joke, "Gee I would give up anything in the world to spend a night with Megan Fox. I wouldn't care if I were married or if she were married. So who is your favorite man that you would do the same?" Keep it only as a joke. If she says that it is Wilmer Valderrama or whoever, you can guess that she is persuadable but if she comes out and scolds you for even asking that question or says that she will never do it because she is committed to her husband, you will know that you low probability of convincing her.

Making a married woman have a no-strings-attached relationship is no easy task if she is not the one to suggest it, but the #1 thing that makes it happen is complete trust in the man. She must know in her heart that you are a man that can be trusted so gain it. Do not gossip with her (it will make you come across as a man who likes to share secrets) and be there for him when she needs you.
