What is going to happen?

So pretty much, if you haven't heard my story before or can't remember, I started dating this girl in a long distance relationship. It is an hour flight to see her, but I don't see her that often. About once a month because of how much it costs to see her. Anyways, when we first started dating, I was working and getting out of the house and having a good time. She finally came out to see me and I quit my job just before she did. I haven't been able to find a job since then, and because of it, I have become pretty much broke and I don't get out of my house and it is affecting my relationship. We talk every night and when our relationship was younger, we had lots to talk about. Since I have quit my job, a lot of our conversations have become about how we love each other and how much we miss each other. She wants me to move out to Edmonton, and I want to go, but she is the only reason I would. I am just not ready for a move that big. I have not matured enough and I am just not prepared for something like that. She told me last night that she has been having doubts about our relationship and questioning if it is really meant to be, and if I am honest with myself, so have I. I have been trying to hide it because it is so hard for me to find a girlfriend, but the spark we started with just isn't there anymore. I am not sure what to do, cause I do love her, but can I sacrafice everything I have for her? I used to think so, not so much anymore. I just don't know anymore.... :'(
