I have a small question about go back and come back
What option is more suitable in this case?
I'm talking to my friend who lives in Russia (I've been there recently) through cell phone... Now I'm in Brazil my Country...
And then I want to tell her I'll go/come back to Russia next year...
Should I use go or come here
Russia is far from where I'm now (so I first thought about using "go"), but Russia is in the direction of my friend the listener (so I should use come?)
Which one is correct in this situation? What's more natural?
Thank you in advance..
