Actually, my H moved out under totally false pretenses. A few weeks after he dropped the bomb he came to me (he was still living at home) and said he had been doing some thinking and reading about "controlled separations" and he would like to try one. He and I spent a few days really talking about the guidelines of the "controlled separation". He went to his grandparents house which was empty at the time. He and I saw each other once a few days after he moved out then he admitted to me he had lied to me, he didn't want to do the controlled separation and he pretended he wanted to just so he had an easy way to move out.
The rest of his things were packed/boxed up and left for him to collect. This was two years ago. Now he lives with OW and their R is still going strong. Their affair began while we were married and has lasted. So, it is what it is.
