Is It Wise To Go Out With An Ex Girlfriend, Boyfriend Wife,or Husband?

Is it wise to go out with an ex girlfriend, boyfriend wife,or husband even when we have had new relationships?Sometimes,it happens that we slip back into relationships that we had been into in the past.Does this usually help our present relationships?And,Most importantly,is this a safe practice?

well i don't think it is really wise to do that, because it takes only the grace of God for such relationship to continue and even if it does, things can never be the same as it used to be.
