Pam, My thoughts and prayers are with you today. I know this hurts but please try and keep in mind that this man that went to the courthouse today to divorce you is not who he used to be, he is a sad sad shell of that man. He has been influenced by a woman who used her friendship with you to take him away and he let her. She has even convinced him he had to go after more money in your settlement, when in fact if he just wanted it over, he would have walked away. I hope you stuck to your guns regarding the settlement and did not give in, he wanted out, he owed you. They are in for a big surprise as we all know. Their lives will not be what they expect as they have no compassion or decency and quite frankly deserve each other. It was mean and hurtful of him to tell you today of all days that he plans to marry her. He most likely wanted you to get upset and angry so he could justify what he is doing today. Let him go, he is not worthy of you. You have compassion and grace and would never intentionally hurt someone you cared about to get what you wanted. They will not be happy and if they do manage to create a life together it will only be because he cant admit he made a mistake, but this is not your problem. Someday, someone will come into your life and make you see that your are a wonderful, lovely caring woman. He will love you and want you in his life for all time. You will see, I promise. In the meantime, hold your head high, let the hurt come, feel it, and move on. You can do this. Regarding being his friend, maybe in time, a long time, but for now, Why? He isnt really a friend, as friends dont do this to each other. He is gone for now, whether or not he has the courage to be himself again and own up to what he is doing, only time will tell.
Live well, be strong and take comfort in the fact that you tried and are a better person for it.
