Many brides have said to me that they feel like the last weeks before their wedding were out of their control. I always compare it to a boulder rolling downhill, things happen fast and you lose grasp on some things – everything you have planned for is now happening and stopping it can seem like the most difficult thing in the world.
But, in reality it only seems that way. It CAN be stopped. And not by running away. If you have serious, serious doubts, you need to sit down and talk to your fiance, parents, friends – no, they don't want to hear it. They will most likely be hurt and upset but they will listen. Better to stop a mistake before it happens and lose money, than running away or going through with the marriage. Running away from it solves nothing – it just means you lost the money and have more lies and doubts and trust issues to face when you get back from where ever you ran to. Going through with the marriage most likely means a level of unhappiness and higher potential for divorce.
A friend of mine used to tell me after giving me tough advice: Easy says, hard does and that applies here. But in the long run a much better choice than the alternatives.
