Emotions like worry and jealously aren't proof of love but are likely to be evidence of insecurity, control, and possessiveness. Love is positive for the lover and for the one loved, and trying to control and possess is not positive for either. Healthy love sets you free, not binds you down. Healthy love involves intimacy that allows freedom, individuality, and growth. I've had experiences of wanting to possess who I loved, and it didn't work -- that kind of love hurt the relationship rather than nurture it. Unfortunately I didn't become aware of the need to cleanse the way I was loving until far into the relationship and much damage had already been done. Such painful experiences have resulted in my being aware of the need to cleanse my love. As the saying goes, good judgment comes from experience, experience comes from bad judgment.
