We all fear D but ultimately it is just a piece of paper. Your old M was already over when he chose someone else. But nothing you do right at this very minute is going to change his mind. He has not had the chance to miss you. Right now you are an annoyance to him.
But time is a great healer. With time, the tempers will subside and he will begin to see past the resentment. He will see you as a person again and not an obstacle he has to overcome in order to be with OW. Once the dust has settled, and there is no you in the picture for them to demonise, then he will begin to see you for you again.
Use the time wisely. This is a journey for you too. It will [censored] but you will come out the other end better for having gone through it. He may come back, he may not. You may want him back, you may not.
Remember D is just a piece of paper. It does not mean that you need to give up hope. That happens when you decide that you are better off without him.
