When it got to where I had to make a choice. The OM was pressuring me to give him reassurances we would be together, and I felt guilty more and more with my husband because he was doing 180s, had gone to a counselor and was visibly making changes. I chose my H. I didn't want to be a part time mom. I didn't like the guilt I felt with the OM, and I knew it was wrong.
AFter making the choice, it was not done, though. I wasn't sure I had made the right choice. Like your wife I thought I never loved my H. I forgot any and all of the good times in our marriage. So, that's where I found this site. I read books. I talked to a priest. I made sure to stop contact of all kind with OM (email, phone, messenger, etc.). A huge turning point was REtrouvaille. I had distinct hope after going there.
We were separated for about 1 1/2 - 2 years or so and my H did nothing. Looked depressed all the time, but didn't talk to me or do anything. Then, when he went to counseling and I saw changes, I told him about the OM. That day was in April of this year. So, that's the time span.
