My friend is always desperate for someone to set her free for a couple of hours a week, just to be able to do the shopping and maybe get her hair done, and for her own doctor's visits. So that would be the greatest gift you could give her - a bit of time to sort herself out. However, she also likes company in the house too, because the whole thing is very stressful and having someone else to speak to is also a rest for her brain. Her OH is better for a change of company too, he behaves better for us than he does for her.
