My ex is also an SLI-Te, I think, while my father is an SLI-0, I believe, so my ex really is an improved version of my father in the sense that she is more like a Mirror than a Supervisor. I should add that divorce didn't mean that my ex and I stopped liking and respecting each other. (She just got me a subscription to the NY Times as a wedding anniversary present, I gave her a ride to the Farmer's Market so she could buy some Begonias.) Divorce did mean that we're never going to live together again, I learned that I no longer need my father's approval, and I discovered Duals.
If she hadn't moved out, I'd still be married to her, living a life that was OK but not great. Her moving out started a cascade of events which broke irrevocably with the past. I don't think we need each other anymore. But that doesn't mean we can't be friends and be nice to each other. We're a lot healthier now, I think. At lease, I feel that I am. I can't speak for her.
