I have work with the Justic system, when someone is caught, they don't want to admit it. I also work with Disable adult, so.... I have heard it so many times. When they say that I am paranoid and delusional, it just cover up your actions, don't want to be responsible for their own actions.
"Jealousy get you no where in life", that been my motto for many years.
Some people when they get jealous, they don't think, just do it without thinking.
Time does heal all wounds, so give yourself time.
Jealousy does affect any relationship, it not worth it to be jealous.
