You will have to make the decision as to whether you want to continue with the marriage and do you think your husband is worth the effort.
You must have some idea about why he wants a divorce, have there been problems in the home, lack of communication, intimacy, stress or possible infidelity.
1.
Sit down with your husband, calmly and discuss about why he wants a divorce.
Don't cry and get upset and plead that you want don't want a divorce, that would show how weak you are as a person and I don't think that your husband would like to see that, he would probably feel disappointed that you have turned into this emotional wreck.
2.
Ask him how you can fix it, what can you do to correct the problem.
You must have had some idea about why he wants a divorce.
If you find that he will not discuss it you will have time when you need to discuss things with regard to the dividing of your assets.

In the meantime look after yourself, don't just think of this traumatic episode with your husband that you are going through as you are going to need as much of your inner strength so what you need to do is to strengthen yourself, inside and out so you can handle these things.
Perhaps your husband is not feeling loved or valued enough, perhaps he cannot express this to you which is why the divorce.
It will be a solo up hill battle for you but well worth it in the end to save your marriage.
You must look at all avenues about why he wants this divorce, maybe he just feels let down because he is not getting the intimacy that he feels he should or feeling so stressed out he cannot talk to you about it.
Don't feel you cannot look elsewhere for help, marriage counseling is one suggestion but make sure that it is one that has been recommended to you.
Check credentials as well as you do not want to find that the counselor is not qualified and that it all has been a waste of time.
