It sounds hard and impossible, but the best thing you can do right now is work on yourself. Keep yourself busy and keep yourself happy.
As people say above - have no expectations. Act 'as if' everything is fine in your life. The more happier you feel, it will continue with little effort. I find that now, months after, I'm feeling really good and actually a bit excited about what might happen. I'm increasingly of the opinion that if you stay positive, then positive things will happen.
My situation is slightly different in that I was unfaithful to my W, but she is the one rushing through D. For me, this was 3-4 months from initial discovery to being served papers and house up for sale.
Do not mention your relationship to your spouse. Drop the rope and let them go. Focus on you.
