Traduko - Rusa-Angla - Давай остановимся на том, что я не свободна и мне...

"and, you know, I'm not single and it is too late etc."
But I read from French, I don't know how it is in the original text

You see/understand, I'm not free and it's too late to change change anything in my life.
I hope we are not going to break up definitively.

Based on the French translation, I would say:

I reflected a lot.
You see, I am not free and for me it is too late to change whatever it is in my life.
I hope we are not going to break up definitively.

I've been thinking a lot.
Let's stop on that I'm not single and that it is too late for me to change something in my life.
I hope, we don't lose each other forever.

Agree with Sweet dreams for the end of this sentence: "to change whatever it is in my life.".
Better than my suggestion. What concerns "reflected" it's stronger than "thought about". Quite good too.

Hi Sunny, could you help us with the source text?

En partant de la traduction en français, il n'y a pas fidèlement la traduction de "tu comprends" et de "libre", je mettrai "you know, I am not free".
La dernière phrase est négative en français (et aussi en russe) alors pourquoi avoir donné une périphrase ? Je suggère "I hope that we will not break (our relationship) definitively"

The first sentence needs to be improved for further understanding.

When I have a look on the French and Turkish versions, I would say:
''I reflected a lot.
You see, I'm not free and it's too late for me to change anything in my life.
I hope we're not going to break up definitely.''

The French doesn't correspond with the English, I agree with what 44hazal44 says above for a better translation.

I aggree with hazal, sweet dreams and gamine too. It doesn't convery the Turkish text. There is nothing about "we should/let's" etc. And the last sentence should be editted.

Based on the Russian text I would translate this way:
"I've been thinking hard.
Let's stop at the point that I am not single and it is too late for me to change something in my life".

And the last sentence literally would be: "I hope we won't completely lose each other".
