I agree with this.
I know I don’t see things the way you guys do, but these two appear to me to genuinely love each other. They both seem happy. I think it’s wonderful that they’re helping people to see that those who are profoundly disabled can, and are entitled to, lead happy and meaningful lives. I can see that at the moment Hannah finds it easy to cope with the demands of caregiving. She doesn’t need to leave the house to earn an income. Her only daily responsibility other than Shane is the dog.
However:
They are living in a bubble that at some stage must burst. Hannah wants to have children. As a mother of 4 who also has to earn a living, I know that even if she doesn’t work outside the home, there is no way that Hannah can have a baby AND continue to be Shane’s sole carer. She doesn’t understand that, but Shane does and that’s why he’s reluctant to have a child. He knows that the only way they can manage a child is to outsource his care and free her up to physically and emotionally care for the child. A child is the one thing that is likely to blow this relationship out of the water, and Shane realises that.
Even without a child, the bubble must burst. Hannah and Shane both need to pursue their own interests, and they can’t both do that while they are tied to each other 24/7/365. I get that during the pandemic the bubble is necessary to safeguard Shane’s health. But once COVID is under control, they need to think realistically about the way forward if they want this relationship to go the distance.
