I can relate to wanting a husband who understands your feelings. It is not necessarily something they can do in a way of actually relating. Some men are better at listening and accepting that you are being honest about where you are or what you are going through. Lots of men feel a need to help or "fix it."
I know polygyny is not something common to many, or even thought of by most. A woman on the forum that married as a 3rd wife remarked once that she felt bad for only wives because they don't have someone to share being a woman with. She felt they were missing out. I think women just have a different kind of support and empathy. I love this other feminine presence in our family! I love her voice, her laugh, her grace, and certainly her cooking too! I liked the idea of being able to build a relationship with someone who wouldn't marry and move away. Someone who would be here after the children grow up. My sisterwife worked on canning chicken and elk bone broth today. She made an amazing pot pie dinner too....all on a wood cook stove. She likes cleaning and does more dusting and polishing around here than I ever did! She is smart, easy to get along with, very thoughtful. She cares about me too....loves my children. She has beautiful children...and I love hers.
