I had same problem but H was right i had not told whole truth. Took 3 years for me to tell truth. H asuured me that it was the lies that was killing the marriage.
So out it came and he has never hated me as much.
Regrets - some. Trouble is that now, everything he asks and the answer he does not like , he thinks its lies.
Very frustrating. Maybe enough talk now. I know your fighting for a marriage but everything you have done so far is not working.....
Try saying enough . I dont think you have nothing to lose now.
