Relationship questions

Two friends have posed really interesting questions about relationships in the last few weeks. Since it took a bit of thought to compose answers, I thought I might as well make a new post rather than long rambly comments to old discussions. Obviously if you object to relationship noodling, especially with religious bits, please feel free to skip this post!

( 1. Describe what a happy romantic relationship looks like? )

( 2. What's your 'philosophy' on romantic relationships / marriage and how does your Judaism inform that? )
