There is always people out there ready to take advantage of our trust. It's a terrible thing but it's true. It has happened to me time and time again. They are not worth our time and/or the pain they cause us. I'd rather be alone than be fooled. I would distance myself from such people because it means I cannot rely on them or trust them as their attempts to fool me only means that I don't count as a person to them. Very painful decision in some cases but surgery is sometimes necessary for healing. For what it counts, I am sorry you had to experience this. I know how bad it can be.
Cheer up and smile. The New Year is nigh. Time for new strength to pursue old dreams, and, if need be, new resolve for new beginnings. God Bless.
