True. And I think, AnnKay, while I understand you wanting to facilitate him bonding with his new baby, you need to look after yourself first. Let OW worry about him and his depression. Turn to friends and family for help, and get ALL the help you need - but from people other than H. Don’t rely on H for ANYTHING.
You really need someone to stay with you the first few weeks, someone who can cook and do laundry and entertain your 3 year old. Set things up so that you are well taken care of without needing H for anything.
