Should I withdraw my MAIT Suit while filing a petition for M.Divorce.

1. I had filed a MAT SUIT(Sec.13) against which my wife filed a W.O along with a petition for alimony(Sec. 24). In her W.O she denies allegations but wants divorce in counter claim.2. Now the Judge officially orders for a Settlement through a court approved Mediator by whom we have undersigned a settlement terms and conditions that says:na. Both of us will file for Mutual Divorce.b. The husband will pay alimony in two parts. (50% before and 50% on the date of 2nd motion)n3. Now my 1st question is that:na. Do I need to withdraw MAT SUIT which is now in final hearing stage? I assume that anyhow I will get divorce based on Claim and Counter claim of divorce as per written admission by both parties.4. Now my 2nd question is that:na. After receiving 50% payment,if the wife plays foul and doesn't give consent/appear on the date of 2nd motion then all these MAT Suit, Mutual divorce, time, money, and effort will go out of hand. In this situation, how can I protect myself legally, pz advise.
