I learned early on what it was like to be manipulated. I won't go into detail , but you really have to know that you are worthy of the love and praise that you give others. It was not easy watching firsthand growing up how narcissistic some people can be. Some people will drain you , but it will only work if you allow it. You have to know how to use reverse psychology. It is one way you won't be taken advantage of. Another is to never ever have your bank account connected nor lend money to people cause of some sob story , because too often will people do some grimey things for money. Lastly , a wise woman once told me not to tell the person you are dating everything about you and your loved ones. You never really know peoples' intentions even if there are YEARS behind the relationship and friendship. Please instill these things into your children. They could be taken advantage of, too. In the world that we live in, you are not unlikely to deal with these things.
