go to your pastor immediately and begin the petition process, now while witnesses including your husband are around to give evidence, which will speed up the process. Most of the delays are caused by difficulty in finding the witnesses. Due to the divorce and circumstances surrounding it, witnesses probably have the facts surrounding your marriage at its inception in mind and will be easier to interview now than later.
A decree of nullity is only granted if the investigation determines that the conditions for a valid marriage and valid consent were not present or operative at the time of the marriage. While events after the marriage may shed light on those circumstances, it does not change them. Money is not an issue, the actual cost is relatively low, and does not even cover all the expenses involved, but is waived in cases of genuine need.
The whole annulment process can be powerfully healing, especially in a case like yours, but since it requires you to examine yourself and all the factors and events of your relationship, it can also be painful, and counselling for yourself, and children if any, should be going on as well. We will be praying for you.
