He may be more connected w/the kids and pets...but you will be the very, very last person he reconnects to and that could be some time down the road. Dig deeper for patience.
I think I would slow down a bit and allow him to initiate sex once in a while. Depression works on their brains and they tend to find us less attractive, as well as their "functions" don't work quite as well and then they think it is us that is creating the problem.
The crisis will take as long as it takes. You are on his clock now, which is very, very SLOW. He is the one that will decide when it ends or if he likes staying in MLC. Nothing you say or do will speed it up, but you can hinder the process by taking his attention away from what he needs to do to heal himself. That's why it's important that you read everything you can on MLC and depression. It's important that you leave him alone as much as possible and give him plenty of space and time....again dig deeper for patience and take the time to educate yourself on MLC and depression. There is a lot of good info on the forum and it's free!
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
