I wonder if those who get jealous easy are selfish in regards to relationships. I have a friend who comments every time my open relationship gets brought up that she couldn't possibly be in an open relationship since she'd be too jealous. She is also a big proponent of fairly conventional relationship dynamics (she's submissive and deferential to her boyfriend, he treats her like she's owned by him and she's okay with that, etc.) and I wonder if jealousy kind of stems from that sort of thinking. I feel like I couldn't possibly be jealous of my girlfriend since I don't feel like it's my place to put any kind of power dynamic over her in our relationship. We consider each other's feelings in everything we do and it works out well and jealousy never enters into it at all. I feel like that's kind of hard to explain and that I'm rambling a bit so I'll stop here.
