No, but it can help you to figure out whether there is still love there underneath all the pain and insanity you've been through.
It can help you to understand that a lot of what you went through was a product of the disease, and not that your partner hated you and wanted you to suffer. It can help you to see your own complicity in some of your suffering, too.
There's a lot of garbage to be cleaned up on both sides of a relationship. When that's done, you're in a better position to see clearly whether you still love your partner and whether you are willing to continue the relationship. The answer will be different for each person.
