Jealousy and rage in a relationship, most often originate in core-relationship needs going unmet for prolonged periods of time. When a primary relationship need like those related to the "attachment emotions" (need to be loved) are frustrated this leads to anxiety and sadness. The anger and Jealousy are just defensive ways of trying to reduce these scary primary emotions.
The best way to deal with these deep emotional needs is to listen for them and learn how to meet them for your partner. If you do this effectively, over time, the jealousy and anger will go away through the corrective emotional experience you provide your partner (if its unmanageable for you try EFT therapy for couples). What a gift of love you are then giving your partner!
