Your perspective is interesting and somewhat enlightening. First, I understand what your saying about him not trusting me, I was certain now I am not. His worry about the other shoe dropping is completely true. However, there are a few things you interjected that are not true.
First, you need to understand WHY I decided to walk away AND why I decided I wanted to try again.
I gave up and became distant after many years of trying to get him to spend more time with me, after going to counselor after counselor only to end up eventually going alone. After him not only condoning verbal abuse from his friends, but him blaming and participating in the verbal abuse and then eventually choosing his friends over his wife. I pursued I chased for 12 years only to spend most of my time trying to make him happy. He was already gone, I gave up because I didn't know what else to do. He moved downstairs over a year before our separation and would only come upstairs at 9 or 10 at night then just want to go to bed or watch a show (of course one he wanted) if we went anywhere it had to do with his work. I understand that because I was the one to say this isn't working it must be because I didn't want to put in any work. The problem was he was content to do what he wanted with whom he wanted and put our relationship on autopilot just expecting me to be upstairs waiting for him and grace me with his presence. Well I waited for years and I cried for years not 6 weeks and I didn't leave because there was someone on the side waiting. I left because I gave up hope that he would never do the work required to make our marriage work. I didn't happen over night, and trust me all I did was try but he believes his girlfriend deserves more than his wife. I tried lightly pursuing it made things worse, he asked me to go away so I am giving him what he ulitimately asked for silence. Nothing else has worked.
