Why did the treaty of paris strain the american alliance with the french?

This was because France was in bigger debt at the end of the Revolutionary war, because they helped the colonists win the war. They had to borrow money to help the colonists, and it put them in a worse financial situation than they were already in. The colonists didnt help them much with that after the war ended.
