Why the sudden change

So last night my sweetie comes in and he is excited and definately knows that he wants to move back home to ny now. im wondering why the sudden change and how come your so sure now. he stated that the chance i gave him, he wants to give me back the same chance and move back to ny. im excited and cant believe that we might actually be doing this. but i know he misses it as much as i do. i figure the more he chats with his friends, the more he is ready to go back. he stated that we both are changed people since leaving ny. yes thats very true and that makes me wonder, if thats the reason why we left, because we needed a change? or because we needed to grow within ourselves? who knows. maybe its just our time. a lady once told me that i would be going back home and i didnt know when, but by next year maybe it will be clearere to me.
