You are not the fool! Fools know nothing of love and sacrifice.
I am so sorry. I wish I had some answers for you. I just don't understand people, like our spouses, who don't have any regard for truth and honesty. Why lie over and over again? Pure selfishness is all I can fathom.
I think at this point, morally speaking, it doesn't matter whether you file or he files. Biblically speaking you are now well within your right to seek a divorce. It's your choice now.
I don't have a clue on the legal aspect. I am afraid your H may be going to do nothing but cake eat at this point, forcing you to file. That is so wrong, so injurious. Doubly so.
I hope and pray he will come to his senses. But some people are determined to be short sighted.
