Always wanting a divorce, then not. Real or BP?

I'm stuck in this never ending cycle of unmet needs in my marriage, which makes me want to leave.
I stay because I have a child.

I want to go, then we talk & try to work things out but never get far.
My moods are always shifting & his complacency keeps driving me down.

Is it all bipolar? I feel like he "triggers" my depression.

It is getting worse & I have been suicidally depressed this past week.

It's like which came first, are the problems a result of bipolar swings or are the problems real & bipolar intensifies it?

Gosh, I feel so stuck. I hate this trapped feeling. Not knowing if I can trust my feelings.
I don't know what is real or not.

If it was me, the problems would trigger depression, but the depression would be much worse and last longer because of my bipolar. That's what I have experienced with my family and relationship problems.

It took A six month separation for me to realize that my husband os my best friend than I needed in this life

I currently want a divorce because my husband's an *** when manic. I think it's the bp for me.
