Requesting relationship help?

[MrCoffee]

Hey guys,
I got a question. I've been dating a girl for about a month now, and shes ****ing amazing, plays video games, pretty, etc...anyway I find something I have trouble doing with her is talking, when we are hanging out one on one, lots of time we will be playing something like Soul Caliber 3 or SSB, or just sitting together, but when I try to initiate conversation she usually gives one word answers or very short that are impossible to go somewhere with. By nature shes a quiet person but that shouldn't exclude talking completely.

Any suggestions?
