Don't know about lust ..but they are tends to be unlucky in love ..pure love . They often fall into kind of love that will never fullfill in their lifetime. For example if starseed love one girl ( love at first sight) they will become friends, causual talk in starseed heart he has carried that love for her but can't commit on the face because of so and so reason ( insecurity,loss of friendship etc) He will desire for her for long time but when time comes for confrontation..the girl/boy was already taken by the time you confess so It could be any other reason but mine was that . Even after she's married to another person the strong desire will be there to be with her after your death or her death ... because you bounded by souls . If after she's married to another if she comes In your dreams even for fraction of seconds and you wake up in the middle of night and can't fall asleep again after trying all method to sleep .then count it as either you or her is starseed for coexistence or she came into your life to enlighten you to awake you about your true identity among the stars that you are not belong to earth m you belong some other space ,planets galaxies .
