I think that's likely partially true. I've thought that he is narcissistic before. But because he has good times i don't know if maybe that's part of it or if maybe there's bipolar instead/also or something else going on. He has no sense of impulse control. Can't stop himself from bad behavior like drinking and gambling. Becomes emotionally abusive. Then suddenly for a week or two he comes good. Still lazy but not horrid to be around anymore.
What's ironic is that I've helped others get out of relationships with toxic spouses, and yet i stay with my own. Go figure.
As for worse, pain is all subjective. There is not really a worse, because they all are valid xo
