And there is something else I read, it said that during the process of reconciliation, the couple contantly doubts they will be successful. At some point, it is VERY effective if they just "agree" that no matter what "it IS going to work". No doubts, no buts, no what ifs irrelevant to current feelings. It takes the weight off the shoulders.
You husband sounds like if he is second guessing your marriage, his choice etc. Maybe he is tired of not "knowing" things "will be ok". I know you are. Just a thought, Stay strong K
