I think maybe you'll never find out why your H initiated contact in the first plaoce, or why he lied about his R with the OW. But please don't think that he wanted to check he was not making a mistake, I think it's more likely that he is still going through his MLC or that he is has personal issues and missed you.
Take care of yourself, it must be such a difficult thing to deal which, Esporta it came out of the blue.

“There is freedom waiting for you, On the breezes of the sky, And you ask "What if I fall?" Oh but my darling, What if you fly?”
