My attny was very strong in his stance that once one spouse sues the other for something the odds are VERY high it will happen again. He was more speaking along the lines of reconciling and not the initial phases of a separation or divorce.

And I also agree w/Puppy (re: nice/mean flip flopping). My H does the same thing. This week he is "nice" because we are getting down to the wire and he knows our final dissolution is around the corner.

What the two of you decide to do as far as your marriage goes will probably take some time to figure out. IMO the subject of the children should be handled by attnys (or at least guided by an attny). She sued you once and it's not unlikely it will happen again.
