Trying to support my boyfriend become a streamer?

Recently my boyfriend has decided to become a game streamer. I think that’s great and I’ve been trying to be supportive but I’m realizing he doesn’t seem to want my support and tells me about it afterwards. I understand if he wants it to be his thing but it does hurt because gaming is something we both used to do. He did mention things from my past and said he thinks I can’t handle him streaming. I feel if I don’t ask about it he says I’m not supporting him but if I do he then says I’m jealous. He’s only started this for a week and I do worry he will be upset if he doesn’t become popular but I also don’t want to be blamed. My boyfriend is in his 40’s and I’m wondering if this is normal behavior?
