Some of you may already be writing down various things that you discover; either to keep track of all the information or for use as evidence later on but there's another kind of writing that you may want to try.
For me, it started out as a letter to my WW. We always had communication issues and she was refusing to talk to me after D-Day so I began to write down what I wanted to say to her.
It went through several revisions over the course of a week; as my feelings and mood changed, so did the letter. It went through the most dramatic changes after I started reading and posting on SI. I revised the parts of the letter where I was taking blame and I was able to put 100% of the responsibility for her choices, on her.
It was extremely cathartic to be able to really flesh out exactly how I was feeling.
I was able to give WW the 4 page letter and watch as she read it. I received no response or feedback after she was finished but when she left, WW asked for a copy so she could take it with her.
Soon after, I began another letter. This one was quite a bit less angry and harsh and a lot more introspective. I looked at things that had happened in the marriage and could see many warning signs and how I contributed to some of the problems in the marriage (but without taking any responsibility for the A, that was her choice).
This letter also went through several revisions and I was able to see that I was codependent and was sacrificing too much of myself to give her what I thought she wanted.
I was able to give WW this most recent letter and told her to read it when she gets back to her new apartment.
I plan to keep on writing, even if I never give WW any of the rest of what I write.
I find that it's handy to have the computer nearby; you never know when a new idea or revelation will strike you and let's face it, are attention span isn't that great during this time of grief, so it's good to get it written down so you don't forget.
I hope this helps others as much as it has helped me.
Take care of yourselves and like my MIL says, drink water, its good for your brain.
