Why does my messages on yahoo keep failing to send??

[Michael Novio]

This is really pissing me off! So here's how it started..I went on facebook seeing a message from this girl and she said she wanted to talk to me by Email (Everything was in Japanese and she lives in Japan and I live in the USA) I don't know why but when i tried to reply to her message on facebook, It wouldn't allow me to, nor did it allow me to view her profile! it said "sorry this link is broken or deactivated" so i did talk to her by Email...at first my messages were being sent successfully, but then after a few days i've been getting notifications by email saying that "Your message cannot be sent" If this keeps up, shes gonna think im avoiding her or whatever and i HATE ignoring good friends when they are trying to talk to me. I cannot deal with this any longer! please help me! I would appreciate it.
