I love my boyfriend, but I dont want to go to his house anymore

I love my boyfriend very dearly, we've been together for three years. We have a long distance realationship, he lives in Australia and I in New York. These entire 3 years I've gone to his house, in Victoria. I recently came home from a year long stay, and I was just hoping maybe he can come here, well he kept giving me the run around saying he needs to raise the money, he did this for six months. Now he wants me to come back, which is great, but this year I really want to go to school, I want to keep my job, I want to grow up in a sense. I'm suppose to go this week, but I have no idea about how to tell him without hurting him. I've tryed everything to get him over here, I've offered to pay for the whole trip, half the trip anything, but it doesn't work. I've been making myself physically sick over this. I don't want to start my life over again for the 3rd time. I don't want to go, but I don't want to push him away.

Before you go anywhere, the two of you need to make a long term commitment on whether you are going to stay together and where you would live. Under the current arrangement you can waste half your life spinning your wheels then he finds another girlfriend. The keyword is "commitment..."
