Teppo.....my only advice would be to take your S into consideration knowing that you and your W are going to be heavily involved with each other for the next 20 yrs or so.
I have 2 daughters that are 8 and 6.......I do not want them to feel awkward around me or my W no matter what issues we have with each other. My parents got D'd when I was in kindergarten and they both did not speak well about the other person. It effected me as I got older in life because I always tried to keep the peace and avoided situations where they would be in the same room.
