He thinks he's ridding himself of the last piece of his life that may be causing his unhappiness....his M. He has to find out the hard way that you are not his problem either, he is.
I agree with this. I think he does have to find out the hard way that you are not the cause of his unhappiness. He is definitely running from his problems by volunteering for another deployment.
I remember after my H had filed and I had already moved back home I asked him if he was finally happy. He had everything he wanted, he was living with OW, I was gone and we were just waiting on the judge to grant the D. He told me "The stress of the D is clouding my happiness." It wasn't stressful, we had agreed on everything and I was 1000 miles away....but he was still blaming me for his unhappiness.
Unfortunately I think your H may need this D or at least a LS to prove to him that it isn't the magic bullet.
I am so glad you are finished with you last exam ever!! I hope you are doing ok today.
