He wants control so badly that he'll do anything to push your buttons. Being nice and offering to sit with the boys and then poking at you about their bedrooms, etc. Please don't buy into his drama.
Your xh is acting out once again...lights, camera, action! So, the drama continues.....just listen and then allow his nonsense to roll off your back. Mlcers love to hear themselves talk and they love to strut and preen when they think they have control and can manipulate you. Please, please do not buy into his drama. The only person who gets aggravated will be you if you spar w/him over his nonsense and that's what he wants...attention...good or bad.
You know what the truth is and so does your lawyer.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
