undonelife, I read a couple of your back posts before answering here and I notice that you have had a massive amount of TT discovered in just this last month - evidence that he's been continuing to lie to you throughout the 9 months of R preceding this discovery - and that's enough to really be considered another D-Day in my opinion. Certainly enough to set you back emotionally to your original D-Day anyway.
So, given that, I think it's very natural that you are feeling the way you do right now, as he hasn't done anything much to win your renewed respect yet. It's only been one month since your last big discovery and proof of his continued lies.
I think what I'd do in your place is give myself just a little more time for these new revelations to settle down just a bit, because this is all still so very raw and painful - and then see if my feelings changed any. It's a lot to absorb in just one month.
But equally, if the continued lies were too much for you and you really do feel done - then maybe you really are done - and there's nothing to feel guilty about by admitting that to him, or to yourself. You've given this R attempt 9 months and maybe this last TT about the continued lies was the last straw for you, and that's OK too. Only you know what you can live with and you don't have to offer R.
