Did I overreacted?

Dating for a few weeks. He said:

"You cannot love one person it's biologically impossible"

"I have married friends they love each other but they do other things too"

I was like what about being faithful? He said you can if you love someone

I got shocked & upset, but I didn't want to fight. We fell asleep together. I woke up, left and never talked to him again

Did I overreact?
