Long-distance friend likes me but rarely texts me.

I initiate contact, write detailed responses and try to ask interesting questions. The friend has told me a few months ago that they are a very busy person and I respect that. But this same person apparently also has enough free time to read lengthy posts from others and share and comment about them on Twitter, and to like posts and make posts often on Twitter, which leads me to believe that he isn’t so busy that he wouldn’t be able to respond to my texts for days, if ever. I think that it’s odd that I might ask him a question such as what he’s looking forward to about a trip he plans to take, and he looks at it but never responds, but he asks me the occasional question and I answer him thoughtfully and quickly. I ask the vast majority of questions and, while I compose detailed replies, he typically only writes a very brief or single-word answer.

I care and like this person very much. I don’t want to eventually push him away, but I also don’t want to feel ignored. I asked him about the lack of response and he told me that he hopes I don’t feel bad and that he’s just very busy.
