I agree. I think his behavior was inappropriate—he obviously did have feelings for MW, imo, but was stringing KA along. The other anecdotes about leaving her behind on rides when she couldn’t keep up, it seems like he was cruel to her and just didn’t like her that much. He should have removed her from his life.
OTOH, she seems to have been very controlling and in a sense took over some aspects of his life (financial accounts and business) where splitting became more complicated. She inherently knew this man didn’t love her but then dug in deeper to force it. He himself is immature and probably lives outside reality a bit. Investments and bank accounts are beneath him, he just wants to be a cyclist. Totally happy to have KA adult for him. It made it hard for that necessary separation to happen.
I do really see some elements where he seems a little on the spectrum to me. The uncontrolled anger in court, inability to handle rational adult decisions. Hyperfocus on minutae in some of the testimony. KA seems very intelligent and I gather enjoyed that power and control over him.
