I think "işte bu yüzden" is what you need.

I think it is a bad movie with wrong ideas about Ottoman history

by the way, I´ve just realized that it is nonsense

"ne yaz ne kışı bekler"

I think try to say this: "ne yaz kışı, ne kış yazı bekler"

="neither the summer waits for the winter, nor the winter waits for the summer" (they don´t wait each other, they just flow...)

This is a song by Rafet El Roman. You can find whole translation here:

 good job

Everyone needs education

I accept this as a compliment 

The reason is not only "vowel". The point is the pronounciation. kalp finishes with a light "l" as if the last vowel were treble/soft like e. This is like the other words, generally from Arabic:

saat > saatler

sadakat > sadakatsiz

etc

kalbini

...konuşmadığım için özür dilerim...

Well, maybe I should apologize because of my poor English. You are right about the confusion. -meden/-madan is like without the activity has done, for that reason, [activity A] without [Activity B] is Activity A is done or will done or can be done before the Activity B. But that doesn´t mean it will certainly be done, or it doesn´t mean we wish that will be done. That is just the idea: 

[activity B]+madan [activity A] = Activity B can be happen before Activity A

There is no meaning here like "before"
