Wants2Fly, I couldn't have said it better myself- that is excellently put! While I do understand why this question was posted, I think this is the kind of dangerous thinking that leads people quick to divorce or think that what they have is not "good enough". You even mentioned that you were watching a movie and it made you think of that question. That is why sometimes I despise romantic movies, romance novels, etc. I heard recently that the reason (probably one of many!) that Jessica Simpson divorced her husband was because she watched "The Notebook" and realized that they didn't connect like that.

I'm definately not advocating staying with someone if you're unhappy But I do agree with Wants2Fly- to say we need someone else to make us "happy" is a dangerous game to play and we are setting ourselves up for failure. Maybe being content and comfortable can feel a little boring every now again- that's okay- that's when you put in a little effort. Here are two fitting cliches to end on:

The grass is always greener... AND
If it aint' broke...
