I am very sorry to hear that he's gotten far worse than a few short months ago. He's traveling downt the crisis road, and yes, he's exhibiting a lot of mlc traits. The crying tells me that he's a very confused puppy. His sister is dying and he's in denial and doesn't want to accept this. Also, it bring mortality more in his face than ever before.
Now, about the passports. You can always request new ones. Be honest and state that you do not know where they are at the moment or they were taken. You need to protect yourself and start planning for your future and your daughter's. Do not rely on this man for anything. You have to be the stronger one now.
Ireland should have some type of laws to help you and your child. Have you checked into this? It's time to start doing more research and find some support groups that help people in just your type of situation. Your h shouldn't be allowed to get away w/not providing for his family.
Please take care of yourself.
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.
