Should I get her a gift? What do you think?!!?

Should I buy my friend a birthday gift? Here's the story...

She never came out on my birthday... She said she was going to, but then just ignored my calls.

She never got me a gift for my birthday.

She invited me to her birthday, but asked me to pay for my own hotel room, which I have no problem with, but I'm not invited out, she expects me to hold her her drunken *** out from drowning in the toilet. (Mind you every time she drinks, she get SMASHED and I have to take care of her. The one time I was puking and she was sober, she didn't help take care of me, I took care of myself.)

She had friends over for drinks at her house last weekend, and didn't even invite me.

Since she started dating this new guy, she's basically blown me off, and I don't see her much.

AND SHE IS SUPPOSED TO BE ONE OF MY CLOSEST FRIENDS!!

I'm not asking if she's a true friends or anything... Cause I still love the old her, and I know she'll be back to the normal her after she breaks up with the jerk she's seeing. And I'm not planning on going to her birthday, I mean I'm not her mother, I don't want to take care of her drunk *** again, while she's puking on me... Just if I should get her a present?
