Hi Haunted- Happy birthday! Glad you had a good day.
Keep posting as you will receive phenomenal support and advice. I don't have a lot of advice to offer you but you will obtain some clarity about all this the more you read about MLC and depression.
My H didn't look me in the eyes for months and he has lived at home throughout his MLC. Having witnessed this whole process firsthand I can attest to the fact that there is a basic MLC script, there are huge variations to how they journey through MLC and despite the fact that they seem happy, there is a deep, deep depression at work.
Definitely read everything you can and focus on taking care of you and your daughter.
