This has been curious to me, too. So he’s just laying low? I wonder if what happened is not at all what LK said, and RG knows it, and might even have to tell his side of it. RG, now ‘boyfriend’ and not ‘fiance’. RG may well have to testify. “Tell you what, RG, we let all that ‘unlicensed contractor’ stuff go, but you have to tell the truth, here.”
If he knows something different than LK is saying, and he was an unlicensed contractor, he may have been told he’d be better off not suing, and better off not perpetuating her stories, because he may be asked on the stand about them.
Just my speculation. Just my thoughts.
