The day you filed, you made a promise that you would let go and see where things went.
And, this is one of those turns that twisted in the sitch. It's not right the L did not contact you, and I think he's a very protective L, which can be a good thing.
Also, remember this. We all know, well enough now, after all this time with the nutty MLCer, that nothing will really make or break this whole thing. Sometimes the "worst" things end up being good, or having some positive, and things you thought would be "good" turn out to not mean anything at all.
You are not harming H for things he did not do...or in ways he does not truly expect to deserve at this point. You can point out the truth if you wish. But, looking at the big picture, H's mess-ups far outweigh anything you have taken action upon.
Rest easy. I'm not saying this is nothing, but we can sweat it all the time.
Let's see where this goes. Maybe another nudge for your H to fall?
You mentioned OW living in the new home being the last card...if that is true, then perhaps your L acting to your protection might be good after all.
