Also, if there is no independence from Britain, more events like the Boston Massacre will occur. To elaborate, if you continue to see your enemy who is trying to control you, then it is likely that you will fight against them. The British soldiers will also continue to injure the colonists.
Lastly, if there is no independence, then America will never have the chance to decide on its own. The king will continue to ignore petitions and the colonists. If the British continue to be there, the colonists' protests will become more violent.
In a nutshell, the only option that the colonies have is to become independent from Great Britain.
