hang in there. As to the what ifs. You acknowledge you are cordial to each other, you have kids together, she sees you.
The more you stick to "the plan" the more likely a reconciliation might be around the corner. Right?
As to detaching. I know that when I have friends it is less easy for me to give an excuse to just stay home. Even going to see a movie or go for a walk can help clear your mind.
