Grief is such a personal thing anyway. Everyone does it so differently. So to say someone should feel like this or that after the end of something is not really fair.
The best story I heard about a widow was this one:
The widow was being comforted by her friends at her husbands funeral. They told her how lovely the service was and she remarked that it did cost a bit but luckily she had enough left for a stone. "Headstone?" remarked her friend. "No, the 5 carat kind of stone I'm getting for myself! That s.o.b. never bought me anything!"
