Leo loves to be seen, so there's a problem if the Lion suddenly stays home, avoids groups, or tries to be inconspicuous.
Is Leo's spirit waning like the ashy death throes of a fading star? Perhaps your usually sunny mate has turned bitter and jealous or begun to growl, yet refuses to say what's wrong.
If things have become too boring, the Lion could be on the prowl for a more appreciative audience. You may have done nothing worse than offer too little praise or too many directives, but you may be able to win a Leo's heart back - little gestures and proclamations of your feelings, STAT! And go out after!
