Mission accomplished!
Now i just need to know how formal this "arrangement" is...is it bad if im only talking to her like twice a week?
We see each other and party/bang once a week.

Other than that time, am i meant to talk to her often as if shes a gf? Or only like twice a week?

Cheers!

i'm no expert on this subject, but i would think that any "normal" schedule of conversing would start to get weird (relationship'ish?)

why not just call each other when you want to hook up? what is there to talk about if you fuck when you are together but aren't in a relationship?

sports?

the usual M.O. when it comes to fuck buddy the conversation usually goes like:

You: "what ya up to this weekend?"
Her: "idk why?"
You: "keep it free i may roll through"

or

You: around 1 am "so what you up to?"
Her: "blah blah blah"
You: "Maybe we can meet up later =)"

you don't make it a habit to talk to them unless you are messing around that day or plotting a day to mess around. If they are your fuck buddy there is no need to dress up what YOU want. You already did all the prep work before she became your fuck buddy. She isn't a potential girl you are going to mess around with, don't complicate things.
