As a person with a bipolar parent I won’t go near a bipolar person if I can help it. They’re often ok if you’re not too close but it’s only a matter of time until they flip on you and the nature of the disorder is inherently self reinforcing, like most personality disorders. I know some people with bipolar claim to manage with meds and what not but they’re still always off in noticeable ways and I’ve never met a bipolar person I would trust to stay on their meds with out constant supervision and enforcement, idk why so many bipolar people love going off their meds so much but in my experience it’s universal and most will lie to you that they’re still taking them even when it’s obvious they’re not.
I’m sorry you’re both dealing with this and I’m sorry my comment isn’t positive but in my nearly 40 years on this earth that’s what my experience with bipolar people has been
