Hi, this is a quick response because I am briefly on-line and then I have to run.
What you are hearing is standard MLC script. They do think we are high maintenance. We give them nothing, in their eyes, and require relating to. We continue to arouse complicated emotions in them, we are not a quick fix. remember, 'Lazy, selfish and entitled' when they are in MLC. Harsh, but sadly true.
Divorce of itself does not change the underlying situation. They think it will 'clarify' things.
Please note he is still finding reasons to blame you with his 'high maintenance' comment If you honestly are, then face it. Some people are, but often they are worth it anyway. But likely you are not, just a normal human being with normal needs.
Try not to worry so much about what your h thinks and feels until he comes out of this. It doesn't much matter, as it will change from day to day, hour to hour. You are still very focused on him and his crazy world, which doesn't make sense most of the time. What we do need is for them not to have any emotional or other power over us, so take it back.
