Very interesting facts. Like you said, the email doesn't seem like a R, so H is just lost, looking for a way out of his own mess.
He needs more time, and unfortunately it means more time for you on a waiting. On the positive side, it is also a sign that things are not working or didn't work at all with OW he had before.
He may still be feeling lonely, lost and trying to have reasons or he is in MLC, what will take some time to get back into his senses again.
Oh well, at least you have your fluffy cat now and he seems like a very gentle one.
