Help with translation of text, please~

Aw, I need your help, dear people, who are studying Japanese. ^^" I have little text which I need to translate into romaji. Please, help if you can.

Text:
Everything has gone. You understand me, don't you? Time changes everything. Feelings disappear sooner or later. I knew that some day we'll have to say "Goodbye". You also knew it.

It hurts, but we both have to understand that life isn't over. So... Goodbye?

Sorry for my bad English xD I translated this text from Russian so it could have some mistakes.

I think it would be something like:

'Subete wa inakunatteshimatta. Anata wa watashi no koto wakaru deshou? Jikan wa subete wo kawaru. Omoi wa (sorry, don't know how to translate "sooner or later". You could probably use the word "itsuka", which means "someday" here >.<) kieteshimau. Itsuka wa "Sayonara" to iwanakucha tte koto watashi wa shitteta. Anata mo sore wo sitteta.

Itai kedo, futari wa jinsei ga owatta tte koto wo wakaranakutewa ikenai. Dakara... sayonara'

Somebody correct me if I'm wrong, this is only my third year of studying Japanese..

Hope that was of some help ^^

Oh, thank you very much ^^ It really helped me.

You're welcome ^^

Good job! Remember to keep to either plain or formal form >< (just one small variation of darou as deshou, but I often forget and make that bumble as well). I'm just a Japanese language student　too, but I've added some things:

'Subete wa inakunatteshimatta. Anata wa watashi no koto ga wakaru darou? Jikan wa subete wo kawaru. Osokare hayakare (or you can use itsuka but you might be too repetitive since it's also used in the next sentence), kimochi (I think it *might* be beter to use kimochi instead of omoi if we're talking about emotion, but I could be wrong) ga kieteshimau. Itsuka, "Sayonara" to iwanakya ikenai to iu koto ga watashi wa wakatteita. Anata mo wakatteita.

Itai kedo, futari wa jinsei ga owatta to iu koto ga wakaranakutewa ikenai. Dakara... sayonara'

(You could use "tte" or "to iu" in the places I've changed it to the latter, depends how informal you wanna get. I also changed some things to make them seem less informal as well, because as a foreign speaker of Japanese, I think it's important we try not to diverge into too much from formal or plain form into moreso 'casual language' yet, especially in the context of the text above ><)
