People actually marry for many different reasons. In our culture (North America, anyway), we tend to marry someone we feel "love" for. But love can be defined many ways. I definitely wouldn't want to marry someone I didn't have a strong physical attraction to, unless we agreed it would be a platonic marriage.

Of course, there are arranged marriages in some parts of the world.

At the least I think the couple would need to be able to communicate well, respect each other, care for each other, and do on.

But remember the vows used in a traditonal marriage. If those vows are used, then I definitely believe the couple should have all the intentions of following them and believe what they are agreeing to.

Hope that helps some, anyway....
