Guys are weird. They often have this thing about not knowing where they fit in anymore, at a deep level, now that women are supposed to be viewed and treated as equals.
Guys often are taught to deal with women in ways that don’t work, by other women. (Mom, grandmother, previous girlfriends.)
Guys are often treated badly by women, and learn to be either cold and heartless, uncertain of themselves, or erratic in their responses. It’s the same in the other direction… nobody’s winning the “Battle of the Sexes”.
Guys are human too. Humans are stuck in these limiting bodies, and f they’re not educated properly about the importance of communication and how to be pro-active about both receiving and returning it, there is often mis-communication and misconception, which turns into feeling threatened by the woman.
I can tell you that I personally admire strong, aggressive intelligent, educated, and tall women. All things that usually threaten a man’s self esteem and sense of self worth. But you put me in a room with a woman who makes me feel inferior intellectually, and I will either start picking her brain like mad or run like hell. The latter response is usually to the ones who are so far above me that I feel like I cannot bridge the gap. Fortunately for me, such women are extremely rare. lol
The point is, if you felt threatened in your self image by someone, why would you want to be subjected to that all the time? Maybe he’s insecure, but when you think about it, he’s no more weird than you and I.
Okay, maybe just you, cause I’m pretty weird sometimes.
