There is a difference between being friends with a WL and dating one. The latter is fraught with emotional nightmares unless you don't care what she is doing all day with other blokes. We all know it is her "job" but as you drop her off at work and then sit at your desk all day wondering what she is being asked to do with these blokes it plays on your mind and you are thinking how many people have fucked her arse / pussy / face today, how many punters made her orgasm, which punters are trying to date her, which punters have been nasty to her or unpolite. Not easy territory.

On the other hand being friends is relatively harmless as you can avoid the emotional side of the relationship. A lot of WL's are quite lonely over here as their families are overseas and they like the connection to a local for days out on their days off, coffee, lunch etc.
