I would like to ask how dark should I be to her at this point? And other than GAL and giving her space is there anything else I should be or could be doing?
Theres only so dark that you can go. You have 4 little kids and are living together. In my opinion, you only really need to talk about the kids/schedules and the finances/house. Otherwise, Id really only talk about inane topics like youd discuss with a friendly neighbor....the weather, tv shows, etc.
As for other things. Well....have you started working on you yet? Have you set goals? Do you have some 180s you are working on?
