Answer:
I would say that their relationship grew tense over time.
Step-by-step explanation:
I may not be right on this one, but I'll give it a shot. I say their relationship grew tense as time passed, then became hostile. Native Americans were exposed to their diseases, which caused a huge amount of deaths for the Native Americans. However they still helped them learn how to grow crops to provide for their families. Though the English began to cross boundaries the Natives set while allowing them to reside on their land. The longer the English stayed, the worse they got. The Trail of Tears is a primary example, when colonizers wanted to move west they relocated many Native American's, who didn't want to be 'Americanized' which killed many in the process.
