Madam
What I understood is your husband married another woman in Turkey and he does not want you go Turkey. First of all double marriage is forbiden according to civil code. So he is unable to marry two woman at the same time.
If you or your attornet set up demand for prosecution the prosecution service will commence a investigation on him.
Secondly the statue of your husband's new wife depends on few criterias. Whether she knows or able to know that her husaband had already been married before the marriage or during the marriage.
