Some quick background info. 22 year old, moved to a college town, army vet bla bla bla.

My question is this, one of my girl friends is a total dime, I'm not interested in her in the least bit as we've been friends since junior year of high school. We basically have agreed to wingman for each other at the bars and parties. How do y'all think this will play out? Any of you have experience with this sort of thing?

Edit: She's like a sister to me, and not in the incestual way.
