It's interesting that the author note actually changes the way I read that strip (especially since the note loaded and thus got read first).
Without the note, the result of Sven and Faye's talk is certainly not, uh, dumpster sex, but it could range anywhere from "Yeah, I guess we can be friends - but nothing more, ever" to "No, I never want to see you again. Don't come near the coffee shop."
With the note, it kind of implies we start with "Don't come near the coffee shop" and goes downhill from there.
Oh well - Sven looks like a classic case of "Don't know what you've got till it's gone" and unfortunately doesn't seem to know of any way to get 'it' back. If he ever finds someone he cares about again, hopefully he'll understand his feelings and summon the ability to say "no" to whoever is trying to seduce him.
As for Faye - she contributed to the downfall of their relationship by insisting it was sex and only sex, which certainly helped Sven treat the relationship as if it was disposable.
Still hoping she doesn't rebound into the arms of Slimegus though.
