My husband is bipolar. We fight like cats and dogs! Its unnerving. Him not sleeping with me is I'm bipolar. Or never spending time with me I'm bipolar. Or getting in his constant moods. I know mostly this is true but.... Ego can step in and cause big issues in a relationship.

The pattern I experience is he does something wrong. Then I get mad. Then he gets mad that I'm mad. Then I'm confused and mad because he's mad that I'm mad. "confusing" Then I want the fight to end. Then I apologize to stop the drama. And nothing gets resolved until we are both rationally thinking and not being so egotistic and having to be right.

Oh and don't argue or contradict what he says. Thats never a fun conversation. If he's wrong keep it to myself besides I really only need to know in my head that I'm right. My ego gets the best of me though occasionally. There's times where I always have to say the last word.

He has a cold shoulder when he's mad the size of Iceland too.

He uses our fights against me and says I'm always starting a fight. Aghhh. Is there any rational with an irrational moment? I don't think so. Its best to walk away until someone humbles and anger is gone. Theres no perfect relationship. Theres just a better way to approach I guess. Its impossible when theres anger involved or hurt feelings.
I think when two people care more about each others happiness than their own and have that as a constant goal things will improve. Its hard if one is being egotistic and selfish. I know a book that really helps me is The Four Agreements by Don Miguel Ruiz. I put it on my blog. I've read it a lot.. Good luck!
That answer any of your questions or create more???? Hope I was helpful.
