so finally I realised that 200mm is sharper and has better focus but 135mm gives photos more close to real, I mean what I see in real with my eyes!

What is your idea of a portrait? There is a huge difference between, for example, a head shot and an environmental portrait. The same framed portrait will give the face a quite different "look" when using an 85mm to using a 200mm, the face will look flatter and fatter with the 200mm ( http://education.niksoftware.com/2012/09/11/how-lens-focal-length-shapes-the-face-controls-perspective-a-lighting-tutorial/ ). Having said that I bet nobody could tell the difference between images shot with either lens unless you put two different images next to each other, particularly if you use advanced techniques like the Brenizer method ( http://www.ryanbrenizer.com/category/brenizer-method/ ).
Unless you really know where you are going with your portraiture, or could post an example or two of where you are now, it makes much more sense to get the 135mm and see where that takes you.
