Can't understand

Backstory: I love writing and poetry a lot. Just helps me cope. I'm not 100% if I want to try to commit it as a career but I still take it serious and try to start up writing a lot. I had a terrible ex who killed my confidence and I lost the old things I worked on. My current boyfriend gave me confidence to start up again. My issue is that when we're awake at 2-4a and I feel I have a amazing idea, write it down, and tell him; he just seems indifferent. Its just confusing. If I try to hint at what he's doing that's bothering me , it just becomes a big issue and its not like its my career or something so idk if im just sensitive. It just doesn't make sense because he wants to push me to write more but doesn't seem like he wants to hear my new works or ideas.
