Your situation is not at all easy to live through right now. But, even if you may find it difficult to accept, please remember, all such agonies pass with time, even though in your present case, you will find it extremely difficult to pass each day for some time. Even when things settle down, this negative life-event is going to leave an emotional scar in your mind. But, like a lot of people who went through such ordeals in their lives, you too will carry on.
In spite of what has been written above, I would suggest you to try your best to keep the communication between both of you alive and active, without involving close relatives, bringing in ego issues, "who is right and who is wrong" fault-finding activities etc. Try to engage in mature exchanges of communication between both of you. Try convincing him for a few sessions of couple counselling with an experienced psychologist. It will be very soothing for both of you if these efforts work. Things will work out if both of you engage into these with maturity and forgiveness.
