You don't ever have to apologizing for feeling something. Or not feeling something. Sweetie, you can't help how you feel. None of that is your fault. And...yeah, it kinda hurt my feelings when you said it was nothing, but I know you didn't mean nothing by it.
It was silly of me to go bringing up my feelings anyway. I shouldn't have done that. I'm really kind of stupid sometimes. But don't worry. We're still gonna be great friends, okay?
