Hi Grace - Don't worry about him speaking to a solicitor. I have spoken to three now and at no point during any of those conversations did I really want to get divorced/separated. I just wanted some reassurance, that in the event of a D, I would not be left high and dry.
The first about a month post BD. I told him in a moment of weakness - I wanted him to know this was SERIOUS. Like you, he did not think it had gone that far ... strangely, he thought telling me that he didn't think he wanted to be in the marriage and then treating me like a leper for a month was not going to make me think the marriage was over .. but I digress ... don't read into it.
