Marriage in and of itself is not very appealing because there is such a wide variety of connotations that society attaches to marriage. On the one hand, there exists the legalistic perspective behind marriage which combines financial and material assets and alters tax recognition. On the other hand, there is the spiritualistic aspect of marriage in which people might be married for the basis of religion or flat out 'high' emotions for one another.

Myself, I see marriage only as a means to express greater long term commitment in a variety of ways. Commitment is nice but I do not think I need the state or the church to recognize my commitments, as this only restricts things to a large degree and potentially marginalizes those who are not married or cannot be married (like homosexuals).

To say all of the problems I have with marriage would also be to probably express a lot of larger problems with the whole of society, even if just American society. All in all - marriage isn't that appealing to me. ;)
