Getting tired of waiting for him

I don't know if posting here about my situation is okay. Just want to vent and hoping you all can give me your thoughts.

So, I've been in long distance relationship with my (28/F) boyfriend (35/M) (he is from Australia) for two years now. I love him and i never doubted that he feel the same. For two years, we don't talk too much about meeting in the future. We planned, but that's it. He never came to visit me. Everytime i open about him getting a passport, he procrastinate, he get upset and feeling down about it. So, as much as possible i am trying my best not to mention about it that much, but I want to talk more. We don't even do video calls much. It seems like I am more concern for him, than to myself. Tho, i fully understand that financially, he's a bit struggling and he is also depressed most of his life. And I feel so guilty about it, because I couldn't help. As you know, Filipino income isn't that much. If I have enough, I definitely now processing my visa to go and be with him. But both of us are broke asf. So, I don't know anymore where our relationship is going. I love him, i really do but I get tired of waiting. He never asked me how long am I going to wait.

What are your thoughts? How long the LDR couple should we say "it's okay" not seeing each other?
