Reading this thread reminded me of a piecw I read on yahoo.com news. People feel about the same way after marriage as before. Meaning if you felt good about yourself before your marriage then afterwards you will feel good about yourself. People who were looking to marriage as an answer for happiness would probably be disappointed.
I would say your title would be more about lust then love. It is hard to slow down, but I think it is the better route. Some people don't get to really know their partner until years after their marriage (I don't have an actual reputable source, but have heard it from a few married friends). Sometimes when they really find out who the other person is they really don't like them or find incompatiabilities. Relationships also change over time as the people in it changes. Sometimes the grow apart etc. I guess most people know this stuff. I just felt like sharing my thoughts.
