I'm going to come at this with a bit different approach. And yes you may have made some mistakes ie. Restraining her. But it don't believe you were doing so in a way intended to harm. Learn from it, don't do it again. And move on.

To me you sound like you are very desperately trying to hold onto this relationship. And I understand that. When we feel like we are loosing someone we love we tend to get that way. I read all the responses here and a lot of talk how to best serve her. What about how to best serve yourself in all this? To me is sounds as tho you have been in a committed relationship with her for quite some time, yes? I'm going to take an unpopular stance here and that is that bipolar or not we are accountable. I would not let someone string me along that I had been committed to for sometime while in the meantime listen to their woes of being confused by the new man at work. In my opinion bipolar or not she needs to make up her mind and not drag this on and on.

That might not be a quick process but I really think you need to step back and just focus on what you want. And what you need. I have bipolar 1 and it sometimes affects my relationship yes. But I also work very hard to make for the best relationship possible. Relationships can be hard no matter who is involved. I'm not convinced her indecisiveness is directly bipolar related or just a normal thing people go through. What bothers me is that she seems very unconcerned about how you are doing and you seem so concerned about she is doing. Where are "you" in all this.
