I just found out that someone is ignoring me.

The reason I found out was because this person sent me a supportive PM. I went to reply to it and imagine my horror when I find out that this person sent me this supportive PM only to let me know that I've been ignored.

I'm not sure I understand...

Why would this person send me such a PM only to ignore me? Did this person want to hurt me by letting me know in a subtle way that she/he is ignoring me?
