Basically what it sounds like, how can you basically tell a girl (29, used to work together) that you want her as a friend (she's expressed interest) but not completely close the door on the idea of us fucking/whatever down the line.

I've seen an lot of stuff on here about how having female friends isn't worth it etc but in my experience there's a fair few pretty good reasons to have them. Access to their social circle, girl friends etc but let's face it, there's some class women out there that you (for whatever reason), you just don't end up dating.
