I know, I think its pathetic. I suspect many people, maybe most people, are more emotionally dependant then actually in love so this leads to them staying with someone that doesn't really make them happy, to be sure to never be alone, while pursuing other people, which is what they really want to be doing. I think like you said, if you want to pursue other people then leave whoever you are with and be a celibate. I think its pathetic to let the fear of being alone make someone stay in a mediocre relationship rather than following their heart.
