In school, I was only taught why the Patriots decided to split away from the British Empire. However, I was never told why the Loyalists decided to stay. What benefits were Loyalists seeing with staying with the crown? How did they view events like the Boston Tea Party and the Stamp Act? and how did they view Patriots?
There's always more to be said, but in the meantime you may find some answers about the Loyalists' motivations and their fate after Yorktown here and here by u/enygma9753.
It should be noted that even within the Patriot cause, many had believed early on that the King had been led astray or misinformed by his ministers and government and that he may yet be persuaded to address their grievances directly. Many Loyalists shared this belief too and also agreed with the same issues about taxation and lack of representation.
While the Loyalists were more confident that any grievances could still be dealt with through the existing framework of colonial government and appeals to London, the Patriots gradually lost faith in seeking redress from the King as the war wore on, and would become more determined to oppose not just the government in London and its policies, but the Crown itself.
