After dating death spouse
Certainly, new romances won't go well if a grieving person is avoiding the pain of bereavement by immediately replacing one partner with another.
Recovering from a loved-one's death is just not that easy.
In time, they may come round to the idea, but it is a situation that requires kindness and tact on both sides.
And while it's easy to see any criticism by your in-laws as an unnecessary obstacle to your new life, try to remember that they too have had to deal with the loss of your partner.
If your children are still living at home, they will be affected by any new relationship.
If your partner was dying for a long time, the chances are that you did loads of grieving before he or she actually stopped breathing.
You are then more likely to feel ready for a new life than someone whose spouse died suddenly would be.
Even so, it can be helpful to use these stages as a rough guide to help you to understand sudden difficult emotions such as anger.
Recognise too that these emotions are part of a process, and that most other people also feel them.
