That's interesting. I can't see her living on her own in that place as she ages. He is incapable of defending her from any harm but he enables her spending and likes the hedonistic way of life as much as she does. We have heard it said that shd can't travel on her own and the chaos she creates wherever she goes anywhere proves that. At least, he would attempt not to lose tickets or be as late and chaotic as she is so she will see all that as being positive. He is her support animal and maybe that's all she wants: someone she can control to a certain extent and whom she can hold equally responsible if things go wrong. Also, Clara said she dislikes sex, so in that respect, he's perfect for her. She can get away with anything with him by her side, however unlovable and useless he may be.
