So, a short overview of western psychology on interpersonal relationships is: it is okay and healthy to have casual sex as long as you keep to one-night-stand protocol or whatever to make sure both (or more) parties know where they stand; but in case you happen to have that epic love that is so strong you're willing to sacrifice your life for that person — oh, it's just delusion and unhealthy obsession, possibly with a side order of codependency.

I call bullshit.
