In the end, she only seems to move when confronted with the prospect of something bad. She wouldn't have seen a doctor on her own if I had not said I wanted a divorce. Of course now, she started getting off her a** and doing chores around the house yesterday. Will probably last a week or so before she just goes back to the old routine.
Regardless, some therapy for myself would do some good. And anti-depressants may help me see things is a clearer and more positive way.
In a way, I can't really stand living like this anymore and think the amount of damage in the relationship is past the point of no return. But the whole divorce prospect is also scary as there are a lot of unknowns there for me.
