As I read this stuff I can't believe how well you are handling all of it. I know you probably feel like it's all falling apart, but I look up to you as you have continually done the right thing and nothing you will regret later. Your entire support system is under attack and you haven't done one regretfull thing. If this is a test your getting 100 percent. I have a strong faith in God to and when everything falls apart for me it is the one thing that holds everything together. As for that preacher, pray for him a lot, forgive him and read Luke 12:48-49 every time you feel the sting of what he did to you:
And that servant who knew his master's will, but did not make ready or act according to his will, shall receive a severe beating. But he who did not know, and did what deserved a beating, shall receive a light beating. Every one to whom much is given, of him will much be required; and of him to whom men commit much they will demand the more.
I belong to a prayer group also and when ever anyone is under the kind of incomprehensible attack that you are, they fast. I know that might sound unusual, but you are being tested right now, and tempted. Remember that Jesus fasted for 40 days and nights and the Devil couldn't touch him. That is the best possible advice I can give you although some non-religious members might not understand. If you do fast you will be blown away by the results, trust me. I see your immense pain, but I think your actions are kicking butt and I will remember this when if I ever go through anything like this. I congratulate you again for the way you are handling it. Hang in there.
