Because my ex has had a couple of periods like this, which contributed to our relationship becoming unworkable. Yet now he is as lovely as he's ever been, and I feel confused and am wondering if I was imagining his destructive highs and long lows, and their fallout. And also, I'm wondering could I have somehow caused him to behave as he did? Because he's in a new relationship now, and seems very balanced, calm, fair, reasonable - while I find it difficult to be pleasant around him because of how much he hurt DS and I when he was last 'up'. And being the frosty, more emotional one in the face of his 'niceness', I feel as though I must be the one with mental health issues. A part of me I'm not proud of wants to see him have another high/low, purely to reassure me that I haven't lost the plot and my instincts haven't been failing me. (A psychiatrist my ex is seeing is undecided as to whether he has full-blown bipolar disorder or not.)
I feel as though my head has been royally screwed with in recent years, and now, in the moment, he is fine and I'm a bit of a wreck.
Argh. Can living with someone with borderline/undiagnosed/unmanaged bipolar play with one's head like this?
