6. Shows interest in all that the man does
Another indication is that the woman would show interest in all the activities that the man does, irrespective of how manly these activities are. If a man plays video games, plays guitar, goes horse riding, goes racing, sits at home playing FIFA with his friends or goes for any other activities which women do not normally do; if he observes that the woman is showing interest in all those activities and probably wants to join him as well then it means that she is deeply in love with him.
It is simply due to the fact that we make an exception for those we love, for those that matter most to us. So even though a woman might have the least bit of interest in how free kicks are done in football or how to gain plus points in a video game and so forth, and yet she is still there with you asking about all of that, making you show her how to do the things you like then what more could it mean if not for her love and devotion to you?
Seeing you happy and excited talking about your interests makes her happy and that is why she bothers enough to spend all that time getting to know what those interests are and why they have caught your attention. She also knows it will make you more interested in getting to know her in return if she does so. It does not matter how boring that activity is, a woman would show interest if she really loves him and she would want to know more about these activities along with all the other things that the man does in his daily life.
