I don't know if anyone has taken this side, so I'm just gonna assume they haven't.
my husband is bi-polar (and currently unmedicated, we're in the process of switching doctors) and I wouldn't leave him FOR ANYTHING. I'm not gonna lie, it's not pretty sometimes. Sometimes it's all I can do to keep from walking out, but what I keep in mind is that IT IS NOT HIS FAULT, NOR WHO HE REALLY IS. I mostly just ignore the moodswings. If he needs to cry, or be depressed, he does it. I ignore it. I tell him I love him, and I support him and I'm here for him if he needs to talk, but I refuse to fight with him, or cater to his "woe is me". Is it hard sometimes? Yes, very. Is it worth it? Of course, I love him. And when he's normal, we're perfect.
Maybe this comes from the fact that I'm a broken person myself, I can't have children, and I've been left because of that. It sucks to be left by someone who loves you, and that you love, over something you -really- can't help. I can also tell you as a woman, the "leave me and find someone better" gig is for ATTENTION. she doesn't really mean it, and if you do leave her for someone else, it's gonna break her heart.
Do you mind if I ask how old you are? I'm 29, and I've been with my husband since I was 24. I know that before my previous marriage and divorce, I wouldn't have been able to handle someone like this, but I gained perspective. Have a talk with her when she seems like she's not cycling, and tell her that you love and support her, but when she's up -down - up -down and stuff, you're going to leave her be. Make sure she won't hurt herself or others, and then let her just get through it.
it takes an incredible amount of support and patience to be with someone who is bi-polar, especially one who rapid cycles. I'll be keeping you in my prayers :3

Funny, my husband is a diagnosed, unmedicated bi-polar, and he doesn't throw guilt trips, blame me for things I didn't do, or just BLOW money. He does get upset and sad for no reason or at REALLY stupid things, but then will flip a switch at the drop of a hat and be SUPER happy for no reason...he laughs at inappropriate times, gets mad at the world, ect ect, but he rarely takes anything out on me.
maybe it comes from him living with a bi-polar parent, so he grew up with someone bi-polar and fights really hard to not give into it, I dunno.
