You aren't jealous in the least, and it's a very good thing. You are content with your own life, and you're proud of who you are. And you are able to be truly happy when a friend has things go their way. You're confident, capable, and full of high self esteem. Keep it up!
You possess an ideal balance of passion and compassion. You definitely can get swept away and lose your head a little. But you're rarely a fool for love!
