Was this girl being rude to me on Facebook?

[Music Man]

There is this one girl on Facebook who deleted my comment that I've sent her yet she has enough time to respond back to her other friends' comments and I'm really pissed off at her for deleting my comments cause I've always tried being a good friend to her, the comments I would write on her Facebook wall is asking her how she's doing and what she'll be doing for certain Holidays such as Christmas or Thanksgiving.

I happen to have a learning disability and the kind of friends who she writes back to are those who were popular in school, we're now in our 30s.

When it comes to old friendships I wanna continue where we've left off but sadly many people don't seem to feel the same about me.
