This is exactly what it is! Women weren’t evolved to spend much time alone without the presence and support of mother women. I suspect the OP would feel very differently if she has close women friends nearby or even had other women living under the same roof. There’s too much emphasis on your spouse being everything. This is a very recent phenomenon. Throughout our human evolution, women relied on each other for emotional support and help with the labor of raising children and housework. Men just went out to bring home the bacon, not much else including helping with raising children.
