4. IF William was gay, Ella couldn't expect Maria to live as she had done (the humiliation, gossip etc.) so she didn't know about it.
maybe. but there
are varying shades of grey, don't forget. the reason for the hasty engagement, seems to have been that Ella had recently decided what she wanted to do with the rest of her life (the convent etc), but she still had responsibilities (ie: Marie). she didn't feel she could really begin work towards that goal, until she'd gotten Marie married. her eyes were on a "bigger" prize, so-to-speak.
5. Maria was very prone to self-pity & I do not give full credence to all she writes (primarily because her descriptions of Ella conflict with so many other children's - Felix, Anna Vyrubova (who later had no reason to like Ella yet still praised her care for children) Marie of Edinburgh & her mother etc. etc.)
but she didn't
resent those other children. Marie & Dmitri
lived under the same roof & were constant reminders of the children she'd never have. and the huge amount of love that Serge poured onto them must have galled her to the core. he seems to have loved children, but couldn't (or wouldn't) give her any. she watched him dote on someone else's children. i'd bet they (the children -- Marie & Dmitri) were the only chink in her armor. she dealt with, and handled, most everything else with the unfluttered grace, decorum and positivity for which she was known, or would come to be known.....except for Marie & Dmitri. her feelings betrayed her where they were concerned... whether she tried to suppress it or not, the pain & resentment she felt because of them & towards them, surfaced as icy aloofness. and Marie bore the brunt of it.
6. If Maria wanted a convenient excuse to escape from an unhappy marriage, Ella & Serge gave her a good idea for an excuse.
i've read EDUCATION OF A PRINCESS several times, and i don't remember her alluding to her husband's sexuality. in fact, i don't remember her
ever mentioning it. imo, she kept her counsel quite well. i heard about Wilhelm through & from other sources.
