Anyone so insensitive to ask you out or want to go out with you while the coffin is till warm is probably not the best choice for a date.
When my husband died I told the children I would never get married again.
I felt this way until approximately 18 months and when I met the right one I started dating again and married him.
I also love both my parents and although I know it would be hard to see them with someone else I would never wish them to be lonely in the time they have left.
GROW UP and love your Mother because one day your "best friend" will be gone as well and you will be sorry.
This is the result Your mother may have been your best friend but she never had a best friend in you from your answer.
