I do think you should send her a light email. I wouldn't say "I'm not ignoring you" because she'll just use that to pick a fight. I also wouldn't tell her you love her, because that would just make her angry.

I very much like the idea of a short email mentioning something funny that happened or something you saw that you just wanted to share with her.

She'll probably ignore it or send you a scathing reply, but that's okay. You'll have taken away her ability to say "He's ignoring me" to herself.

Continue to send a fun, short email every few days.

What are her top ENs? I'm guessing conversation is one. What are her others?
