We had been talking for more than 3 months and we had seen each other through the cell phone. We met in Madrid a couple of months before I moved to London (he travelled to Madrid for vacation), and it didn't work because he was too busy all the time with his job and I got bored, actually.
I did once: I moved to London, and I was there for a year... but it didn't work. I came back to Spain afterwards.
How long did you guys speak for before you moved there? Had you met before hand already? Also why it didn't work out if you don't mind me asking
