Thank you all for all your help and suggestions, the thing is she is not interested in anything, no puzzels, no tv, no magazines, and most days until 12-1 pm she is very sleepy so she is not up to much.
I do take her out sometimes but she soon forgets and that is when she gets really angry, she complains that she never goes anywhere etc. She gets very very annoyed if her partner leaves her side, but he is fine and likes to do his own thing, he is very good and spend most of the day by her side, but he likes to go out and about and as soon as she realizes he is not by her side she gets so agitated that she wears herself out to the point that she doesn't even have any strength left to eat anything. She even gets quite violent.
I feel i am not doing enough to contribute to her wellbeing.
I think she might need to be reassessed again by the doctors as perhaps she needs her medication changed, she might need something that will help her not to get so agitated /violent and upset when her partner is not by her side, because she is never alone, i am always by her side and so is he apart from a few hours a day that he likes to go and do a few things.
Thank you all again for all your suggestions
