When I got hit with BD I went into full research mode. I found a lot of anti-D, save your marriage experts and authors. MWD being one of them. They agreed on some things, they disagreed on some things. But universally, all of them, whether they were the "don't pressure or pursue type", or the "reconnect and work on showing love type", agreed one thing: DO NOT DO MC.
MC has a very low success rate. In fact, most of the experts said that the one thing that virtually guaranteed a D was MC.
Now if you read my threads you'll see that my W and I did MC. However, I should point out that the MC we did was less MC and more IC for me with her present. MC should be reserved for couples with both people committed to saving the marriage. Once she got on board then our sessions transitioned to more traditional MC.
