Read this for advice about texting. It's for women complaining about men texting but applies to you too.

It's very needy complaining about texting. Also texting is a very "personal preference" thing. Some people like it; some people don't. If I'm v. busy I won't look at my phone.
Re: Facebook deleting
Serious question - how old are you?
It was a very childish thing to do but whatever your age, not likely to have the result you were after.
If you are a bit older, plenty of older people on Facebook use it very rarely. Personally, I wouldn't notice if someone deleted me from Facebook. I don't used it to chat, I use direct email.
If you are younger, she probably has 1000+ friends and may not notice until she wants to look at your page/message you - which if you are text communicating she may not pick up on for a while.
As to advice, you have lost a lot of ground here by being very needy. I would back off for a bit.
And just be a bit cooler.
Once enough time has gone by, maybe leave it til after Christmas, ask her out for a date. But be casual and relaxed about it.
