You know, Kimmerz, these guys look for anything to blame except themselves. You owe him no explanations. You did nothing wrong. He is faced with a consequence of his actions and now he cannot handle it. Reality check and he expects you to clean up after him.
If it makes you feel better my Ex does the same. It's my fault if the kids and him don't see eye to eye or if they do not get along with OW. I told J he needs to clean up his side of the street because I wasn't doing it anymore.
Let them work it out. If he blames you again, then let him have it or else walk away. Whatever feels right to you.
Just my two cents.
