How not to irritate your loved ones with special interests

I haven't been on here much as

a) the site has been very slow to load and

b) I just got a new special interest, which feels very much like an addiction for me at first.

I'm just wondering how other people manage when they're in the initial throes of a new obsession and only want to talk about that obsession, but their family/friends have zero interest in it?

I'm very aware that my poor husband has to put up with this quite often and he gets quite p'd off with me constantly quoting things or trying to share videos that to me are the most interesting things in the world but to him hold no interest.

It's not even like you can share your excitement with other autistic people as the likelihood is that they won't share your interest either and we're generally even worse at feigning interest.

So do most people just keep it to themselves? Wait until it's less intense? Or do you seek out online communities?

My current special interest is a musician who is very famous so there are lots of pubescent girls posting hundreds of photos but it's not a sexual thing at all for me and I wouldn't want to chat with a load of teenagers. Years ago there were lots of fan forums for most TV shows and bands but they all seem to have vanished.

I'm rambling but I'd be interested to hear others' experiences and feelings on this.

Thank you.
