Feelings of jealousy usually stem from when we feel like we have no value, when we are jealous we tend to search for evidence to prove that someone else carries value over us. We need to take our eyes off of others and turn them inward, create self value for ourselves, if you do not love yourself or can truly believe that you are loved, no matter who you are with or how loving your partner is, you will always feel they value someone else more than you. Try hard to heal your past wounds and let go of the past bitterness; find the seeds of jealousy that lie deep within you and build emotional security in its place. Eventually you will be the one that others envy, then you will remember the pain you felt and reach out to them and guide them to heal as well.
