I am sorry if I offended you, I didn’t know you were divorced. As to the Shiddich Crisis 40 days before a child is born it is decreed who it should marry. Here on earth it is harder to find who you are preordained to marry. There is no sign saying that she belongs to so and so which is why there is a crisis.
As far a Loshan Horah is concerned a lot depends as to was asked for example if you asked did X kill Y then you must answer truthfully, but if asked how was their relationship you can claim you don’t know. It all depends how it’s interpreted.
