Financial talk

I've been seeing my BF for over a year now. We're not living together and the financial strain is too overwhelming being a single mom. So I've decided that I'd like to go home back to CA for better money. My BF is not at all open to the idea of going with me and he has no future plans of living with me. With all that understood how should I go about being his GF in the mean time. Do you think that it would be better to start the separation process now? I'm moving next spring and anytime that I bring up the subject he is uninterested. I would love for him to come with me but he is not at all warm to that idea. For over a year now he knows that I've had financial difficulties and I've mentioned the idea of moving before so this is not out of left field. I wish he could be supportive I would like to talk to him about this without him looking away. I know that this might be difficult for him but he's the one who says that he wants his own space and likes the freedom of living alone. I'd just would like to have his support and attention on the matter. I feel like he's not going to be of any help no matter if I stay or if I go. So the only option that I have is to do what is best for me and my daughter.
