hi amy - glad your ok now. This is a horrible place we are all in. hmmm OW is who she is. Morally dead. you wont be able to stop your kids being exposed in the long run and as they get older , that will work in your favor.
You on the other hand have every right to detest her and set boundries to protect yourself. I think it would only be unhealthy if you were acting on that hate - phone call, slashing tires , that kind of thing. It is healthy to recognise that she is a whore and that without your help, karma will catch up with her.
a story I heard today - a man left his wife and kids 10 years ago for this OW. They were together 4 years and broke up. Then after a short time reunited. The OW now has bone cancer and life expectancy is short. Now the LBW ( who was telling me the story ) is not sad. she has moved on, remarried, raised 2 lovely children. but will she shed a tear - NO. Does she believe justice has been served - Yes.
Her hatred was healthy and pushed her along. There are appropriate levels of anger and hate for all situations and absolutely encessary. God would not of given us the emotion if not to help us.
