I think you have sound judgment for going dark. If you feel like you are getting very little from your convo's and all you are doing is regressing emotionally then do it for as long as you feel comfortable. Take your time getting back to her or not getting back to her for a bit. I agree with Lost and Denver on this buddy.
Buy a bottle of wine and really go dark! I did that 3 weeks ago and went dark for about 14 hours only it wasn't 1 bottle is was 3. When I woke up I thought I was going to need an IV
