Re: Those aren't fighting words, dear - READ THIS
This is an interesting article, every situation's different but at least it gives some food for thought. It's hard to be in a relationship when you're not settled in your individual self, and sometimes a person may go through some kind of midlife crisis or individual identity crisis and it feels like it can't be resolved within the relationship. Luckily this woman gave her husband the space to sort out his individual issues while still being able to be inside the family system. People are always changing so two partners can never know what changes will come along, but when each person respects the other's autonomy it can help a lot.
