Weddings are optional. I don't understand why most people think otherwise. I've heard many people telling me that they don't believe in marriage for the sole reason that it's too expensive.
You are correct a Wedding is very optional. I am doing it for her more so than myself. Then again it is almost always for the lady not the guy. Though thanks to doing Volunteer work my whole life I have made some good connections that I can pull favors from to make it a very inexpensive wedding. Yay for doing good deeds.
