The first is simply to verify the thesis I laid out above. Talk to her about the way she interacts with guys that come on to her. Try to understand why she engages in what you, and most other reasonable observers, would consider flirtatious behavior. It may be the case that she does so for the reasons I’ve set out, or something close to them. If that is the case, then it is best to let the matter alone. She can’t help the way she looks, and she has figured out a way to make the best of the great gifts that nature has bestowed upon her. In speaking to her, you may discover that flirting-as-coping doesn’t come into it at all. She flirts for pure enjoyment. If that is the case, you should do the same thing: flirt with other girls when she is around—especially when she is around. As you may have already noticed, a beautiful woman on your arm makes you even more appealing to other women. Your girl already knows this. Using her looks to attract the attention of other women is a more than suitable revenge for her outrages against you. Your final option is to break up with her. The idea is not as crazy as it sounds. Not every guy can handle going out with a breathtakingly beautiful woman. Being in a state of constant anxiety and anger over whether your girl is being hit on and fondled, and enjoying it, is no way to live. You have had multiple nights of mind-blowing sex with the most beautiful women you’ve ever seen. That is a great life experience. It may be time to move on to a woman who is much less stressful to be with.
