Damn... i don't want this to fall apart 😢

I met my current boo in Florida(I live in georgia) and we made it official, 3 weeks ago. He was really attentive and really excited to talk to me. I really like him. He is kinda depressed we can't see eachother rn because either of us have the money to drive somewhere to meet. I reassured him I will wait and that I love him and will not see anyone else. He said he really loves me but it kills him to not be with me. Boo has been replying to my texts late and not video calling me like him used to. He'll open and reply to my texts like 5-12 hrs late. It makes me so sad. When I ask him what he's even doing he says "missing me and loving me," then disappears for another how many hours. yesterday he told me I've been really amazing and he loves me even more. He said I've been so patient and too good to him. I also asked him if he still feels me and he said ofcourse and was confused why I asked. thoughts?
