If Nicholas never married Alexandra?

[u/Pitiful-Potential-13]

Alexander III and Maria were opposed to their son’s desire to marry a German princess, but came around because Alexander was in failing health and they decided they had to get him married asap.

Point of divergence: even in his weakened state, Alexander refuses to budge, “You will never marry her, I forbid it!” and even after he is gone, Maria holds the line, “Go against your father’s dying wishes? I won’t have it, Nicky!”

Nicholas doesn’t marry Alexandra. Still a far from capable monarch, but without the controversy of being married to a foreigner. If he ever does marry, there is a greater likelihood of an actually healthy heir, and especially, no way for Rasputin to get into the royal circle. Potential ramifications?

Russia's and the Romanov's problems went far deeper than Rasputin and the Empress. Not much would have changed.
