my husband sometimes comes home for lunch.......
Yes, I agree that's a possibility. It's just something I'm putting out there - since they are young and in love.
My husband never once in our lives came home at noon from work to actually eat lunch, although I'd call and invite him home to eat lunch. So I just thought I'd put that out there.
Because I think that's the relationship they likely had. He was asked home for "lunch", and then she disappeared.
