Is it normal for people to change really long standing behaviour when they realise that divorce is really on the cards?

[WHATISTHISNIGHTMARE]

Just that really. And how long will the change in behaviour last?

Am beyond confused.

I suppose that it if I were to back down after 2 days of slightly different behaviour and still a lot of blame and not understanding my position, it would make a mockery of me and everything I have been through over the past few years and especially this last one.

It really hurts though.

Have considered the hoovering aspect and think there could be an element of this, yes.
