Wow. Way to paint everyone with the same brush. Of course, you're right--ALL people with bipolar disorder are EXACTLY the same, they all mistreat and blame their significant others, and they're all flighty as hell, too, moving on to their next relationship without a care in the world. There certainly doesn't exist anyone with bipolar disorder anywhere in creation that does not evince every last one of the traits you list. They absolutely don't deserve to have relationships with people without disorders, either. Hey, I know! We could stick them all together somewhere convenient, you know, in a camp or something. Then they wouldn't interfere with all those normal folks.
A lot of people come here in search of support, and a lot come here to support others. You seem to have a pretty clearly defined agenda, one that only involves telling people that those with bipolar disorder are not worth their time or love.
I sincerely hope you manage to let go of your overwhelming bitterness, however well-deserved you might feel it is, before it does you in.
