Welcome! I have done quite a bit of reading on jealousy. In our quad, where two male egos tend to rock the boat frequently, we have learned that being able to verbalize the jealous thoughts goes a long way to diffuse them. Just being able to say, " This makes me uncomfortable, and I feel jealous of ---" immediately opens the heart and mind to a more compassionate place. When those feelings are not expressed, they become huge and seem impossible to overcome. We have also discovered, more often than not, we are not alone in our feelings. Someone else in our quad almost always can relate. Communication, patience, sharing, and a willingness to move slowly have been SO very important in our own experience. Good luck to you and your loved ones. It's not an easy path, but I have found it completely worth the effort!!
