Thanks for all the advise, I wish I had found this forum months ago!
Yesterday I got home around 7pm, my wife was sleeping in the couch with her meditation/relaxing music in the background. She was completely drained, I think it had to do with our discussion the night before maybe also the scare of the accident. I tried my best to get the kids to leave her alone so she could rest, she slept all the way through until this morning. She was going to cook something but I got everybody pizza and wings so she wouldn't have to worry about anything.
This morning she was her usual distant self, I did get a chance to wish her a good day and she responded. Touched her back, she didn't move away as she sometimes does. Not reading too much into that, but her reactions are not always consistent.
Tomorrow will be interesting because its halloween. Not sure if we're going to walk with our 5 year old together or if she's going to ask me to just go with her by myself.
This weekend is her "weekend with the kids". I usually stay around the house, but I'm thinking of making myself scarce and do something fun. She's kind of taken advantage of me on those weekends by asking me to stay with the kids while she goes to do something else. Sunday is one of our daugther's birthday, so no idea what we'll do. The awkwardness continues ...
