A quest for answers, often unknowable ones (though Neptune clouds this fact), and a peace of mind that is believed to follow their attainment, yes... And we often don't realize what's being sacrificed in the process until it's significantly damaged or lost. Even then, there can still be a drive to continue -- sometimes with the hidden conviction: "If I just wait long enough, dive deeply enough into these feelings for 'X' and figure out our entire connection, he/she will come to me!", making it even harder to stop.
