There are others out there like you, "married no kids" and Christian. At least one couple in my area comes to mind (not sure if she is on the forum). I too long for authentic friendship/accountability partners that I can mutually share my heart with. I am a firm believer that we Christians need to actively and biblically fellowship not just eat a meal after church service. If your request is not evidence that we need each other, I do not know what is. There is probably a Christian woman somewhere across the globe that is thinking she is also the only one with no kids, married, judged for her decision not to have children, and lonely because she has not been able to find someone to relate honestly to. I am praying that you find each other. But, in the meantime, open your eyes because you just may find that a sister is right in front of you that you may have never expected to be able to lean on. Bless you.
