Guy texts daily but doesn't seem interested in my hobbies / activities?

A guy i met online seems to give mixed signals. We met in person a couple of times and he has told intimate / personal stuff about himself. He is currently unwell (undiagnosed illness since past few months) and doesn't seem to want to commit. He asked me if i was into him but refused to answer when i asked the same question.
He texts almost daily, usually some news items or forwards etc. But he doesn't respond to or seem interested in anything even remotely personal to me e. g. i shared one of my travel blogs with him and all he did was ask if it had pictures. He doesn't ask how my day was or my hobbies (he did in the beginning). As a result, my walls have started going up and i am avoiding initiating conversations with him. Super confused.

Side note, i am saggittarius and he is a virgo.
