You cannot "finish with your current wife": USCIS will deny your case because you do not live together with her. Unfortunately, you cannot just divorce your wife and "start all over", either. Considering your second wife's petition for you, USCIS will require you to prove that your first marriage was a real one, and that you married your first wife with an intent to create a family, not just to get a green card. Your case is a complicated one, it requires a skillful handling; so you do need an immigration attorney. Considering that USCIS already issued a Notice of Intent to Deny, you have very little time to salvage your chances of becoming an LPR (once USCIS denies your first wife's I-130 petition for you, getting you a green card will become much more difficult).
