Having read some of your sitch I am way further on with a W that has done similar things. I can tell you this, if she is the same, I believe she still loves you. She is just lost. My W lifed in the loft (yours the basement) for 2 years. It doesn't matter which room, it will be the same behaviour. Does she appear unhinged at times, not there mentally?
My W spewed and raged a lot. It stopped when she moved out with the kids. She now talks to me more. I am using the time to GAL and I am happy. She is seeing me happy and I believe is liking what she sees more. She is also asking me for help with things and I am helping, if it suits me. Be careful not to confuse cake eating with being kind. Always be kind.
I am taking the kids off her hands tomorrow to go to the cinema. This will help her get things done. But why not, she will be grateful and she will feel warmer when she sees me as I am caring for the kids and her.
You do need to detach first and let her see you are getting on with your life.
I am happy and you will be too. I hope to reconcile but if we don't I will be fine and so will the kids. W will struggle if we don't get back together and I get the impression she is starting to feel this a little.
All the best mate.
