Hopefully you moving out improves your own environmental health so you can review the situation with some healthy distance. It's hard to feel good in a home that's an unpleasant environment. I'm sorry you are experiencing all this.
When you are ready to review what it is you have got there... since you mention a young kid... could this be postpartum depression? Or depression in general made WORSE by PPD?
The escapism and "going through the motions" made me wonder if that is something that could be considered when you are ready to assess if you still want to be in relationship here or not.
Hang in there, whatever you decide to do.
