I stayed by her bedside to read her stories.
Why did you do that for her? How did you meet anyway?
We met at the cancer support group
That sounds very nice of you!  It's quite considerate of you to take some time to spend with someone you care about!
I bet she's just looking for pity sex and I don't care what the rest of you think.
It's not healthy to assume the opposite gender is only looking to connect with you for sexual relations. It's unlikely that she would use her cancer diagnosis to get pity sex, and it's pretty rude to say something like that.
