Dear Joe:

When I wrote to you last that the argument was not about something small, I didn’t refer specifically and exclusively to the fact that the guy sent you an invite which you declined. I was referring to the facts  that she looked into your phone, invading your privacy, never apologizing for it, and instead justifying it: I looked into your phone because you said you had nothing to hide, she told you.

This means that nothing will stop her in the future from invading your privacy. And that is not “something so small”.

Also, you apologized to her thoroughly but she did not even respond to you for a while and when she did, she was devoid of compassion for you. This is not “something so small” in the context of a supposedly loving relationship.
