Hello, this seems to be an unfortunate situation indeed, however it is not the unpardonable sin, you would not be concerned if it were. This woman seems to have a dual personality, to first marry you then to only choose to communicate with you thru email? This is not normal, then for her to choose to attend your church, after filing for divorce, seems too much for me, she must be vindictive among other things,
it seems that you are better off without her, since it has been a couple of years since this was posted, it is my hopes that your life is much better now!!
