<human>: Hello Reddit! 
I'm using a throwaway but I really want your opinion on something. I met a guy, we'll call him Shane in August. He was a casual hookup but we ended up getting to know each other and spending more time together. We go out about twice a week. I'm a commitment-phobe and he's coming out of a bad relationship, we've both expressed that we aren't ready for a relationship. That being said, I really do like him, and he feels the same way about me. 

We've been seeing each other more and more and we're at that point where we're talking more about our lives and leaning on each other. Recently someone in his family died and he is reaching out to me for supportt. Maybe this isn't a big deal but I see it that way because neither of us are the type to seek out comfort from SO's. I'm happy to support him. 

Here's the big but: I was diagnosed with bipolar disorder this summer (a few months before I met Shane). For the most part, I've been responding well to medication and taking it as directed but it's still getting sorted out. Sometimes I have symptoms that affect my daily life (for example, when I'm having an episode, I get so irritable that I can't be around anyone). Maybe I'm over thinking this but if we're getting into the territory where we lean on each other, I feel like we're getting closer to a relationship and farther away from casual sex/ dating. At what point, if any do I tell Shane that I'm bipolar. When I do, how do I bring it up? I don't want to scare him but at a certain point I feel like he has a right to know even though I don't expect him to support me.

Give me a shortened version of the text
