I don't ever envy someone for their possessions or anything like that.
As far as relationships go, and me getting jealous... I am a very jealous person. If I really care about someone deeply, I get jealous at very little things. I was cheated on by my ex husband and a couple ex boyfriends. Not to mention I am very very insecure about myself. So, I get very jealous about stupid things. Not that I yell at my boyfriend or anything like that, but he can tell I get uncomfortable.
He's never cheated on me, or anything like that. But when the little things get me un comfortable, he catches right on and fixes it.
I wish I knew why I was so insecure... I've tried fixing it, but its much harder than you'd think. For me at least, lol.
