Hi M.-
My experience with "Marraige Counseling" was through the Reformed Church in which my husband and I got married. I was not nervous until the night/day before. I really did not know what to expect but knew that my soon-to-be husband and I had already hashed out a lot of (what we thought were) the "typical" marraige squabbles. This included money management, jobs/careers, housework - both inside and outside and kids. We thought we were covered...
Then we sat down and met with the Reverend. After the niceties, he informed us we would be taking a test! I nearly freaked. He explained that we would actually be taking the same test and that he would "analyze" our answers for the next meeting. I felt like a deer in headlights. LOL. Then I sat down and took the test and the questions were about things that I thought were silly - who would drive the car the most, which way you wanted the toilet paper roll to unroll, toilet seat up or down... Of course there were a few harder ones involving inlaws, holidays and the topics we had discussed personnally like money. I really thought it was quite funny and was rolling on the floor by the time I was done.
Long story short, while the Reverend picked a few select questions to discuss (including the unrolling TP one), what I learned was to listen when my husband spoke and try to be patient. I grew up in a house of 4 kids and I found that the tendency to finish sentences and thoughts really frustrated my husband. He also learned that one of my coping skills - to flee a situation - was not an end of an argument but rather a cooling down period for me. It helped us recognize strengths and weaknesses in our relationship and learn how to take a process we initiated - open communication - to a new and higher level.
For us, the marriage counseling resolidified our commitment to each other and encouraged us that if we continued along our current path that we would remain happily married in the future. Now, this is not to get all wishy washy or to say that our marriage is all peaches and cream, but we have those coping skills to fall back on. The copies of our tests are a great discussion point too and we can see how we have grown and changed through the last 6 years.
I would take this time as an opportunity to learn more about yourself, your soon-to-be husband and your realtionship as a couple. If you truly listen, you may learn something including, as heartbreaking as it might be, that you do not really belong together. Being open-minded is key and if things turn into a "he said/she said" battle than I would have to think twice about the counselor as well as the partner. IMO problems that exist prior to the marriage will generally only intensify and worsen once we accept the burden of marriage (and/or children).
Good luck.
