Be more secure in yourself.
Jealousy most of the time leads to insecurity in yourself. Look, if this person is dating you, then they obviously like you. No one dates someone just for the heck of it. If you can develop more confidence in yourself, than you can help overcome the feeling of jealousy. Being more confident also goes with having a better attitude around your mate. If you’re positive and confident to be around, they’re going to be into you.. If you’re always getting mad, angry, and questioning their motives, or who they are with. You’re just going to make them angry and push them away. Maybe into another persons arms for real this time.
