Not to mention that Sheridan apparently took the fact that Delenn had been the one who'd ordered the eradication of the human race over a tragic misunderstanding in stride. Was he so besotted, did he think with his dick or didn't he give up the position that being married to Delenn meant to him?

IMO, the metamorphosis caused Delenn to completely lose her personality. I still prefer the androgynous appearance of the pilot episode, even though it was perhaps less pretty than the first season version. I've read somewhere that the original metamorphosis would have been Delenn changing from an androgynous being into a female one, but with the prettied-up appearance it probably wouldn't have worked. Too bad.

Also, originally she was supposed to have a relationship with Sinclair, if I remember correctly. That would have made so much more sense.
