A successful relationship is based on honesty. if I were in his shoes, and had bipolar, I would've been real clear about that from the get-go. It's a huge part of who we are. It's also our responsibility to treat it appropriately. We have to be diligent about medications, we have to take care of ourselves. Sounds like none of that was happening. One thing I learned from my divorce, is that no one else can fix your disorder... they can just distract you from it.

If your partner cannot take care of himself, I doubt you will be much good at taking care of you. I hope you preserve yourself, and your loved ones. But don't become another casualty of bipolar, poorly managed.
