I feel like cancelling my wedding!

 I did a court wedding with my husband about a year and three months ago. however, my mother is insisting that we have a white/church wedding too. I have no problem with doing a church wedding but I have made it clear to my husband and my mum that I do not want anything elaborate. I just want blessings in church with our families present and then go home with the family to do a small get together. This is my second marriage, my first marriage was not my choice as it was an arranged married so it was very elaborate. I have always wished to have a small wedding- no fairytale wedding dress and big celebration. Now with this my second marriage that was my choice, I feel like I should be able to make my choice known because after all it is my wedding too and my wishes should be heard. My husband and my pastor are insisting that we have an elaborate wedding and rent a hall. With all my expenses this year, I really don't have the money for a big wedding. I am pregnant and have to save up as much as I can for when the baby arrive. Now this is causing an argument between my husband and I. I really don't know what to do.
