Help to check swedish gramma in the translation

This is the original song in Russian

Iäll listen to the song and try to re-write a little, because your translation is so-so. For example "Ville vara jag din vän" is wrong. Swedish doesn't work like that. "Jag ville vara din vän" would be correct. And again you have "dörr" just floating. Any old "dörr", right, not a specific one..... That whole line also makes no sense in a storytelling/coherency way, but there you might claim poetic license.

It also looks like you've skipped verses, staring with a "då". Like... "where's the beginning of the song?". I know there is nothing before that line, but it's the impression you get. Also, the word "ska" at the end of the second verse might come off too strong. It's like a demand. "Du ska förstå", "I demand that you understand" Also, even though it looks like it, "också" doesn't actually rhyme with "på" or "förstå". Well, again, it might if you're a bit forgiving/poetic license.

First line of the third verse makes very little sense. Actually, most of that verse makes very little sense. 

Oh, well, I'll have a listen. Again, my Rusian is... well, frankly rather bad so I'm mainly just going of your translation, and I'll try to work it around in my head....

Btw, what's the original, Russian title of the song? Using romans?

Thank you very much for you comments. I can not write here cyrillic letters. You can find an original text here:

The second verse is the chorus. It is repeated after verses. First verse is repeated at the end, followed by the chorus. 

There is the whole text, three verses and three choruses. First and third verses are identical.

Den Ensamma Duvan
 
Då kan inte jag förstå, vad jag gjorde fel mot dig
Ville vara jag din vän, förstår du mig
Du gick ut och stängde dörr, en snöstorm är i min själ
Om något går fel, min vän, förlåt du mig 
 
Den ensamma duvan på ett fönster utanför
Tittar in på mig och knackar på
Kanske kommer du till mig också
Du ska förstå, du ska förstå.

Hoppades du bli min vän, men du kunde ej att sa
Och blygsamma ord från dig jag hörde då
Kunde inte jag förstå, överallt den vintern var
Vet du att jag väntar väl på dig ändå.

Den ensamma duvan på ett fönster utanför
Tittar in på mig och knackar på
Kanske kommer du till mig också
Du ska förstå, du ska förstå.

Den ensamma duvan på ett fönster utanför
Tittar in på mig och knackar på
Kanske kommer du till mig också
Du ska förstå, du ska förstå.

Concerning the sense. It is a pop. What is the sense of the pop?

I loved you, you loved me, we have made a mistake, now we are not together, we cry together, I am waiting for you,but you do not come to me...

It is very simple sense. But we like not only the sense, but we like the melody and the voice... And the person who sings, of course :)

I shall think about your comments. How I could improve the sense. I understand that the order of swedish words is very important (concerning your comment on "ville jag"). The Russian language allows more free order of words and is flexible. Unfortunately my Swedish has to be better :) but I am trying to improve my language knowledge.
