T2 you are ok. I love it when someone just says what they feel - no touchy feely, politically correct bullsh*t, just their thoughts.
Trapt, listen, I am old enough to be your mother, so here are my two cents.
This is all new to you. You have never been divorced before. Dealing with a divorce with an MLCer is an added bonus. You need to work your way around it and through it at your own pace, in your own way. You need to feel positive about the steps you take and the reactions you have.
Having said that, I think going back to DB basics may help. Dont go down cheeseless tunnels. When something doesnt work, try something different. Set clear boundaries and reinforce them. Re-assess your actions often and adjust when necessary. Accept your responsibilites, actions and changes. Leave hers to her.
Dont beat yourself up for having trouble adjusting. But, dont stand still either. If it is bothering you, change your actions.
