Separation!!!

Sometimes i really wonder why human must get separate? why can have a proper relationship and a healthy one? Does it means separation will bring a better affects on the relationships? I really puzzle to all... but what i know is i want a normal and healthy relationship that whenever i need someone, he/she can be right beside me. When i fall, he/she can help to carry me up. Is like support, care and love for each other. I realise that my life had been in separation since i was a kid. I face a lot of this and since i was young... i keep this question in my mind until today. "WHY Have To Separate???" Really WHY??? Is like a question marks(?) for me since i was a kid. Until today i still couldn't get the answer because i still living in it. I believe this separation/apart will being facing for the rest of my life. Forever it does not have "this is the last one". I really wonder why does this have to be arrange in our life??!!!
