I'm really sorry about that. Did you tell him that you were just releasing things that bother you?
What he said was incredibly insensitive, and he needs to know that you are hurt. What he said didn't make you feel safe and he needs to know that.

What he needs to understand is that you were just venting, and that a simple solution isn't the answer. While he was trying to make you feel better, he made you feel worse by oversimplifying your feelings. Yeah, those people may not think about what they've done or said, but YOU do and it hurts you still and it's OK to feel that way. It's not like you are looking for anything but to be heard, and I can understand that you feel completely discounted by what he said.

A hug would make you feel more safe than saying something so tactless. I hope you guys discuss this and get through it. And I hope you feel better.
