I really don't think you have any idea of what you're talking about either.
Only the truly inexperienced will resign themselves to one school of thought and leave little to no room for error. The OP is willing to accept that perhaps there is a chance to sustain such feelings in a long-term partner, but the experience of many on this forum suggests that it is highly unlikely.
The fact that you resort to attacking people's personal relationships and calling them inferior signifies that your argument is weak, and you have little ground to stand on. Perhaps you might provide some solid evidence to back up your theories about relationships instead of attacking ours.
