WAW still at home 12 weeks after asking for D

[bdub]

So last night I came home after harvesting. W was packing up stuff from the kitchen. I looked through boxes and cabinets to determine what I needed to replace . I gave her a few things she had left and she gave me a few things she had packed. She went to bed and I sat on the counter in the kitchen and allowed myself to "live with" the reality that she was leaving. There was a lot of tension but we navigated it.
Half an hour later she came out of her room and complained about the lights. I suggested she close the door. This led to an argument. Being flooded emotionally I was not able to keep a level head and it escalated into a half hour fight that culminated in doors slamming (both of us) and curse words.
We both reverted to old habits of criticizing and the atttacking and defending. I should have walked away but didn't.
She left tonight and took the boys to her mom's.
Last night was the last night she will stay in this house. I am both relieved and distraught. 12 weeks of living together after BD was too much stress.
