I third what veritasverify76 stated. Be wise. Be cautious. But more than anything, be Loving. From our experience, if she is not at least attempting to be your BEST friend than you need to be very cautious. Your gut feelings are telling you something. Make sure you are listening carefully. All the advice you have gotten here is great. It was wise on your part to post here for advise. It allows you to step back and look through other objective "eyesight." Too many times we look through our feelings or emotions instead of logic and reason. Our heart can be deceiving. (Jeremiah 17:9 and Proverbs 4:23) Though there is more involved than merely a connection of the mind, each of us needs to use critical thinking skills (not criticism) at first in any relationship before we invest our hearts and spirits. Spiritually you need to weigh the cost of investing. Is there a good return or am I sinking money in an unproductive venture. Many times I have seen individuals invest their soul, heart, then mind and end up with loss. It has been my experience and the experience of many I have communed with on the subject of polygny (over 30 years), that most of the mistakes occur because we do not engage our minds first. When someone brushes off real concerns that you have, that should be a red flag. Maybe the reason my wife and I have never found a 2nd wife is because we are not actively looking for a wife; we are productively seeking a sister that desires to be a wife. We are not looking for a "second wife" either, but to be a wife with my wife, if that makes sense. I am always attentive to the possibility or opportunity, but I stay aware to keep my mind fully engaged. As I've said, "God gave us two eyes, two ears, and one mouth for a divine purpose." And there is a reason why most of the senses are found real close to the brain. Yes, and why our small brains are farther away. When I speak of activity versus productivity, one must first understand the differences in the individual words. To be active, is to be "engaged in action; in a state of existence, progress, or motion." On the other hand, productive means: "having the power to produce, generate, fertile, or create." Activity means to be active in some thing without regard to if it is right. Productivity means more on the line of being fully engaged, mind, body, and spirit in a right thing or things first and then in an efficient way. Okay, ffiinnaallyy my point: When the Word is living in us and it is our filter, then to just be active is not sufficient. We as Believers desire to be productive in all and for all, and polygyny is included. i.e. Loving, growing, nurturing, beneficial, etc. For me, and from the information you have presented, the gentleman seems merely active (immature) in polygyny, his present wife seems not even active, and you are seeing or having questions about whether or not that productivity (maturity) can come of this. Be very cautious; and again, only you can decide by using critical thinking and then keep your emotions or feelings out of it . . . for now. I pray this helps.
