My obsession

Here’s the thing, when I get obsessed with something, I kinda go overboard and I know that about myself. It goes so overboard that it kinda gets annoying. I like to talk about my obsession to my boyfriend and he doesn’t like it too much saying “it’s really annoying” and “just stop” well..when I completely stop talking about it all together, he gets angry saying “I don’t tell him anything anymore.” I don’t know what to do...any advice??
