I used to be an extremely jealous person. Majority of my relationships were spent snooping through emails, looking through phones, and trying my best to catch my boyfriends in lies. I had a lot of problems trusting the people I dated, due to my very first relationship being founded on deceit. Thank goodness I got over this and moved on from jealousy. I could not spend my life jealous, nowadays. It's such a wasted emotion and leaves both parties feeling suffocated. It doesn't cause anything but issues in a relationship.
