Take a good look at the situation. If you suspect someone is cheating on you or if you’re upset because someone has more than you, take a hard look. More than likely, the person you think has passed you up has problems of their own and your lover only has eyes for you.
Respect yourself. Jealousy breeds in our shortcomings and our fears. Stop going over what is going wrong in you and focus on the positive.
Get a third party’s opinion. Talk to a friend or family member who can give you a objective perspective on the situation and your jealous reactions.
Set rules. If it’s jealousy over emails with an old boyfriend, talk about what makes you feel uncomfortable and set rules.
