I guess what I meant is that her reaction does not seem like it is necessarily a result of a mental illness to me -- it's not unusual for people to be extremely conflicted and extremely emotional with stuff like this. I just worry that you might be writing off normal, natural feelings due to her mental illness. I would try to accept them as real, true feelings, whatever they are, whenever they are. If you assume they are connected to the bipolar, it sort of diminishes what she is going through, if that makes sense?

You aren't bipolar, but you decided to leave the relationship and then changed your mind and want to fight to save the marriage. Maybe later on you'll want to leave again, who knows? People are inscrutable in these matters, whatever else they have going on in their heads.

Hopefully you two can work this out for the best. It sounds like it has been a hard road so far - I hope it gets better.
