I have felt like at times my BH is trying to catch me in a lie by asking the same thing over and over.
That was part of it for me, at first. I rephrased my questions in ways that would catch inconsistencies. The one time I thought I caught her - and was devastated by catching her - she made me take out the timeline to see she was, in fact, not TT'ing me.
I wonder if your H's non-verbal communications match his words. Do they?
***************************************
The endless questions and answers never gave me what I thought I wanted - understanding why she cheated - but it had tremendous benefits, such as ...
each honest answer built trust...
each honest answer helped her take responsibility for her A...
each honest answer showed me she was taking responsibility for her a...
etc., etc., etc..

A few months ago, I actually asked a question I had never asked before. Note that I was more than 7 years out....
********************************
In my 2nd year, before asking a question, I started asking myself things like:
Do I know the answer to this Q?
What's the positive outcome of asking this Q?
If I knew the answer, or if I couldn't think of a positive outcome, I didn't ask.
Maybe you're ready for that - but I sure wasn't at 7 months out.
At 7 months, he should be open to, 'That doesn't make sense.' He shouldn't be defensive now ... you ask, he answers truthfully. IMO, he should be able to say something like, 'My thought process was .... I know that doesn't make sense now, but it did then.'
If your gut says he's holding back, your gut is probably right. I don;t really understand attachment theory, but I cannot imagine how any therapy - EFT, Gestalt, TA, CBT, Primal Scream, psychoanalysis, whatever - works when the client/patient isn't coming clean.
