Hi Cooler-j.
Welcome to HealingWell and to the bipolar board, we're very glad to have you.
I'm glad you've already had a look around and seen that you are not alone, that there are others who are in your position, and that you need to get some help. Dealing with an unmedicated, untreated manic person is very tricky and exhausting. She needs to be hospitalized, in all likelihood, but unless she is suicidal or homicidal, nothing you can say or do can make that happen. I don't know what the laws are in the UK, but here in the US, people can only be held for observation, against their will, for 72 hours.
Are you interested in getting out of the marriage? I ask because if you're thinking of divorce I'd suggest getting a lawyer immediately and getting yourself a new place to stay.
If you're going to stay on, though, you're going to have to make some hard ultimatums for her, which are likely to fail. Insist she see a psychiatrist immediately if she wants to you stay. Insist she stick to her medical regimen if she wants you to stay. Be prepared to leave if she says no.
Sorry I don't have nicer responses for you, but I hope this is helpful for you.
