Far too many young royal women seem to have become "servants" to their mothers. Among the most famous: Queen Victoria's youngest daughter, Beatrice, acted as her mother's lifelong assistant, but also was able to marry--very much against her mother's wishes, at least at first--and have a family, before eventually becoming widowed.
Olga Alexandrovna seemed to be headed in the same direction as Toria; her mother did marry her off, but since the marriage was a sham, her situation wasn't much better than Toria's. Fortunately, Olga--like Beatrice--not only fell in love, but also showed some mettle and was able to forge her own life.
Toria was not as fortunate, and many people have remarked upon her mother's selfishness, despite the fact that Queen Alexandra was otherwise very much loved, respected, and admired.
I have read that Toria had something of a youthful crush on Tsarevich Nicholas. As she continued to act as "glorified secretary" to her mother, she did keep albums which included many photos of Nicky and Alix's children. Upon her death her brother, George V, is said to have been inconsolable.
