I'm recently diagnosed with BPD, although I've struggled with my mental health for my entire adult life. I've been working really hard on DBT, attending both individual and group therapy, practicing my skills, etc. I've been dating really minimally during this time because I'm both super busy and focused on therapy. I've kept things casual with anyone I'm seeing and haven't worried about whether I tell them about my BPD because I know it isn't going anywhere.

Welp, in the midst of casual dating I met someone that I actually really like and with whom I can see a relationship developing. I know I need to tell him before we enter into some kind of relationship, but I'm struggling with when and how to bring it up. When do you typically tell someone you're seeing about BPD? How much detail do you go into? How do you bring it up?
