Can somebody please tell me what are the advantages (if any) of divorce straight away or separation agreement then 'no fault divorce' 2 years later? I am concerned about aggravating my inept STBXH with a petition for unreasonable behaviour. Yet he has not changed his behaviour one bit (resentful re kids & practicalities and feeling 'governed by me' - his choice) since we separated in June. I am concerned he will drift into a new relationship and would like to divorce him. It's a minefield. Any advice??
