Am I overreacting to my boyfriend’s comments?

We were talking about the meaning of life, what happened after we pass etc. I said something about not believing in one thing yet I still envision my loved ones up above me etc. I was expressing my contrasting thoughts. He then made two comments that made me feel immediately icked out but also stupid. He said “that’s a basic thought”.. then I questioned him saying that and he said “say something bold”.

It’s the next morning and I am still clearly thinking about his comment. What’s the point in saying that to someone? Does that make someone feel safe to be vulnerable the next time or open up to get even deeper the next time? No lol. It’s not beneficial really to either of us.

Am I overreacting or is this just rude.
