1. In a large pot of boiling salted water, cook tortellini according to package instructions; drain well.
2. Melt butter in a saucepan over medium heat. Add garlic and red pepper flakes, and cook, stirring frequently, until fragrant, about 1 minute. Whisk in flour until lightly browned, about 1 minute.
3. Gradually whisk in milk and half and half, and cook, whisking constantly, until slightly thickened, about 2-3 minutes.
4. Stir in cheeses until melted, about 1-2 minutes. If the mixture is too thick, add more milk as needed; season with salt and pepper, to taste. Stir in tortellini and gently toss to combine.
