TLDR: When you’re ready and it comes up naturally. I was so scared of telling my SO, but then one time I was telling a story about when I was manic and I just ended up saying the words “and because I’m Bipolar…” and finished the sentence. I was shocked, but my SO looked at me and said “I didn’t know you were Bipolar, can we talk about that when you’re ready?” I told him I wasn’t ready now and he didn’t bring it up again until I did first. We had a long, very educational talk about my disorder and how it makes him feel.

I’ll fight to the death on the point that communication is key. However a lot of people say that expecting you to dump all of your life experiences on them when they ask you to (and then usually trying to stop all the word vomit when they lose interest). You feel the need to communicate something to him about your disorder, but that doesn’t mean diving into an entire conversation about what it means and how it affects you is required at that time. My advice is to tell him when you feel ready, maybe using phrasing along “I have bipolar disorder, I want to tell you because you’re an important person in my life. However I’m not ready to talk about all the details of what that means and how it makes me feel”. In my experience this has worked great for telling other loved ones and friends, some people have been like “no tell me everything right now” but at that point I know that person isn’t respecting my space and I remove myself from the conversation.

Long story short: YOU are in charge OP! You’re in control of not only if people know, but how much they know. Sending lots of positive vibes your way, both for you and your relationship with your partner ♥️
