Teenage webcomic romance drama fun times forever GO!
In all seriousness, I've had worries similar to Elliot's. I tend to assume the majority of romantic / physical relationships won't last forever, and I don't think I've ever had an interest in a romantic relationship that has exceeded my interest in a platonic relationship.
Well, unless hugs and cuddling on a sofa requires a more than platonic relationship, in which case perhaps negotiations could be had. Negotiations are romantic, right?
