Maetryx here,
I like being married SO much that I've done it *twice*!
If you married the right person, then you will find that the two of you solve problems well together. That is the ultimate test for deciding to marry someone: Do we solve problems well together? Everything else is just icing (the physical attraction, sharing a political/religious/philosphical view, common interests, etc).
Now that you're already married, my advice is kind of useless. So I offer this other tidbit of wisdom: Beware of escalating expectations.
I used to get giddy when my fiancee made me breakfast or a sandwich. I was in heaven when she sat next to me and leaned up against me. But with time, I start EXPECTING that behaviour rather than appreciating it. Now I find myself getting annoyed if she *doesn't* do the things that I used to thrill me with incredulity (i.e. I couldn't believe anyone would want to do those things for me). But being aware of the problem of expectation creep helps me to remember to appreciate instead of expect.
A relationship, indeed love itself, is all about working. Love may be expressed in poetic words, feelings of giddiness, or passionate sensuality, but love (the verb) is an act of labor, in which an individual determines that the needs and wants of the other are worthy of their time, sweat, attention and priority. The words, feelings and passion are, again, just icing.
