Re: Divorce

pak10, there are a few things which you didn't share that will help us give better advice.
Was your nikkah done in Pakistan? In the nikkah, did the husband give you the power of divorce? Assuming he did not give you the power of divorce, then you can't divorce him. The route of khula'a is always there. More on it, later.
Alternatively if you guys got married in the US, then you can divorce him under US law. Also, under certain conditions, you can get the marriage annulled as well. In any case, get a lawyer who can file the proper court case for you.
Re: khula'a in Pakistan, you can hire a Pakistani lawyer to file the case for you. Search the internet for contact information. In case of khula'a you are required to return the wedding gifts back to him. Depending upon how much fuss he wants to create, this can get messy. Considering he already married again in Pakistan, I am not sure if he would want to prolong the issue. Ideally his second wife will convince him to divorce you fil-fore.
Under no circumstances, it is advisable to remarry without taking care of this issue in a proper legal manner. A muslim woman married to two people at the same time can be very complicated.
