The way people think today

In today's world I have noticed that people are not as kind and friendly as they use to be. We all have our own minds yes but do people have to be so devious, trifling or just plain old wrong? In my life I have ran across plenty of nasty individuals who are looking to only get what they want or need from you everytime they come see you. I recently enountered a guy who treated me like a queen and cared for my kids as if they were his bt in the end he did nothing bt talk bad about me, stalk me and curse at me after we stop talking. In my previous relationship i was well taken care of as long as I did what he needed done until I had his child then he did everything because of his child. I have encountered several women who took advantage of a good man making it hard for a good woman to keep him. There are a shortage of good men and women in the world today because of people doing things to hurt them mentally, physically, emotionally or spiritually. Why hurt people who break their backs to be a part of your life? Why be a careless person when you can be a person of gratitude, honesty, trust and loyalty?
