I want to believe this young woman and give her a better life than that she has had so far. I already have a wife whom I also need to consider.
The problem is she does not want a better life. Also, you do not have to marry her to help her. You do not have to be in a relationship with her to help her. In fact if she has had a life of prostitution she probably needs to know she is worthy of attention WITHOUT ANY STRINGS ATTACHED before she will ever be ready for a normal, functional relationship with another human being.
She is not interested in committing her life to God? then in my opinion she has very little hope of digging herself out of the mess her life has become.
You already have a clear God given responsibility and that is to the wife you are already married to. You have no business bringing this chaos upon anyone else.
Sorry if I sound harsh, but the fact that you cannot clearly see you are not helping anyone in this situation is worrying.
