I can appreciate that you must be going through some difficult times. I have had difficult times too and still live in difficult circumstances. I am an activist and have a multitude of people fighting me to try and stop my work. They will fail of course but in the mean time I have to face every day with a warrior spirit.
Do you want to talk about the issues a little bit. Do you have young children you won't be seeing every day? Leaving a spouse is hard because they have become a part of who you are and you have to make changes that affect the very core of your being. If it is really over and you are getting a divorce then change is inevitable. Think anew. You may meet someone that will make you happy again. This time may be a catalyst to overcome all the ideas that have brought you pain in the past.
