Because to be honest it's none of your business. Divorce is long, tired, tedious unsatisfying process. And it's something he has to kinda do alone and on his own. I'm sure he will tell you later on as time passes.

Many times, manjy men keep things of this nature their own Business and don't want to discuss it unless they feel you have the right to know.
I feel that although you may be in this Relationship, it is all about Something that doesn't pertain to your own Relationship and More in store that he is handling in A... Life he used to have with an Ex.
Don't over think it. Don't feel insulted. His past is own deal and being a raw deal, this is just something he wants to put to bed and Fast.
Good luck. xx
