Why?

Just when you think your life is starting to get on the right track there always seems to be something stopping it..

Recently I've encountered a few bumps in my road.
Why is it that when you say no to someone they feel the need to get back at you? does that make them feel stronger for you hurting them? is that just a defense mechanism?

Do they not realize how bad they will hurt you? do they think that if they hurt you, you will come running back to them in hopes they wont hurt you again? Blackmail much??

Life is full of ups and downs i get that. I've been on a rollercoaster since i was born it seems like, but at what point in your life are you able to get off that ride?

I have this notion that people hurt others, they care about, because they cant stand to see them happy without them in their lives. what i dont get is "Why?"   

Shouldn't you just be able to put the feelings aside and be happy that they are happy, rather then be happy that they are miserable? are you that much of a masochist? 

My life is far from perfect, but i dont need you and your lies making it any harder then it already is. so please, turn around and walk out of my life, and stop pretending to know me, when the truth is you barely know my name.
