We cannot change someone, but we can change oneself?

Hello reader,

It's been almost 3 years that I am with a man and he is really the dreamy person. He's handsome but modest, smart and very popular, incredibly ambitious but so inspiring. It was love at first sight: he didn't expect to meet someone like me and same thing for me. He is +10yrs than me.

He decided to go in a business school in Singapore 6 months after we met. He left me and stayed there for 8 months at the other "corner" of the world. We kept contact via skype or facebook. I just began a job and couldn't have any holidays to see him. He came back near where I worked after 6 months and was still working in his business school (8 months on a campus, 4 months in another campus). We spent 4 wonderful months, we tried to see each other as much as we could, I really have many nice memories of this period.

When his graduated ceremony approached, I learned in a random conversation with some of his friends (who didn't know I was his girlfriend) that his dream was to go back to Singapore - while he said to me "don't worry, I'm gonna find a job near where you live". I asked him if I could follow him over there and he replied that "the life I'm gonna have there is not a life for you". Aww, that hurts a lot especially after one year and a half of "relationship / long distance relationship". I felt betrayed and told him

He went back to Singapore. He stayed there for 8 months and once again, we had weekly Webcam. Months after months, I forgave him and said to him "follow your dreams and ambitions but always remember me". It was very painful for me and I cried a lot, I knew he was having a super-incredible time there (going to Bali, many VIP parties with all the pictures I could see on facebook...)

And then he came back one morning and visit me. He said to me he had very hard time there in Singapore and it wasn't easy for him. He found a job not too far from where I live (only two hours by train) but now, he doesn't find time to see me. He says he's a popular person, he's got lots of people to meet (to develop his "network"), he has a very good job in one of the greatest company in the world and think, drink and dream business. I've been so devoted to him, so crazy about him, I dreamed so many nights about him, I waited so many hours alone and all those sacrifices for this : I see him once every month and a half. I thought our story could be different and I'm wondering if it's gonna work or not. Many of my friends said I'm an incredible person, creative and talented with a big heart but he really abuses of my generosity.

I would like him to change, but we can't change people... I said to him I suffer a lot to be in a relationship with a "ghost" and he said he's gonna work on himself, that he doesn't have a right balance between the business world and me, that he doesn't want to lose me. Some days, he says that "every good thing has an end, even the most beautiful things" and for sure, our story will end one day.

All those months away developed in him an incredible desire of power and ambition (and selfishness?) I can't believe he's that negative regarding us, he sees us like a statistic among other statistics of his life. I would love to make him changes, but how? And how can I accept to live with someone who has this point of view in life? I know I should live him, but trust me there are so many feelings behind this relation. It would kill a part in me - forgive me if I look that dramatic.

Please give me your feedbacks, it will help me.
