I guess I'm saying that I don't believe that the "new" marriage really is better than the "dead" marriage. It's just different and somewhat (a lot) degraded in the trust area. I simply do not buy into the idea that a marriage is rebuilt into something stronger than before.
If that were the case, then we should all betray our trusting spouses so we can make it all better after.
I know that I have thought a lot about what my ex would have to do to regain my trust and I can't see how he would be able to. There are some lines that can't be uncrossed.
