Nlt, Blood is thicker than water and your BIL is trying to look out for his younger brother's best interest. In order for your H to justify his actions to his family and friends he had to make it look like you were to blame for everything. Your BIL is reacting to your H's perception of what has happened in your M. Don't take any of it to heart. Your BIL believes your H's version of the rewritten history of your R.
The others are right. Your H is still very much in his MLC mess - you wouldn't want him back in this state. It would only cause you more pain. He needs to get counselling and heal before he's ready for any R. I am going through this with my H as we speak- he's not emotionally ready to come back to the M.
