Most Christian denominations have trouble with continued sinning when adultery occurs. Jesus' words in Matthew were clear. You seem more upset by the Witnesses not embracing you than your conduct. Unless, of course, there was a divorce first and a reasonable period of time elapsed. Yesterday, headlines were that Newt Gingrich's patriotism caused his many divorces. Have no fear, though voters, because he is now Roman Catholic. Despite his new religion, I wonder if Lloyds of London will insure this marriage.
Most Christians would also say that if repentence is present, it is a matter between God and the two of you. God was present, others were not. Wanting to remain a Witness is Stockholm Syndrome writ large. People keep pointing out Jesus main commandment, to love one another. You can find grace in Christ or you can be a Witness. You cannot control other people. Nothing you can do will change the minds of the Witnesses. Actually, I find the pure drama of your story unreal but others said that when I revealed my Witness history.
Even civil society condemns adultery. Jesus said to sin no more. Christ offers love. He repeatedly said to sinners, your sins are forgiven,sin no more. You are not interested in apostacy but you flee to an apostate site. Aren't you afraid we will infect you? Food for thought.
