Over two years ago I found out about my h's affair and, in the early days, as you may imagine, I was distraught.
A friend advised that I keep a journal and write in it whenever I felt like it. It was a massive help and to date I have filled a whole note book. It is sort of like downloading everything in your head. It gives you a chance to reflect on what has happened and, sometimes, put things into perspective.
I gave up on our marriage at the beginning of last year but, because h lost his job (directly because of the affair) we decided to carry on as normal in the house with the dc until he got another job. He is still looking for another job.
He now wants to give our marriage another chance and I was starting to feel unreasonable about not wanting to. But I went out on my own yesterday, took the train to Edinburgh to do some well deserved sale shopping and I took my journal with me (I hadn't written it it since giving up). I read through what was in there and amazingly I had forgotten some of the shit things h had done. It doesn't seem possible, but I had forgotten the night he told me he didn't want to be my husband anymore then turned over and went to slepp, leaving me sobbing.
I had forgotten the day he told me he would rather leave the family than not speak to his ow again. The human mind is a weird thing. Rather selective in what it remembers.
It was a reality check and I no longer feel unreasonable.
So, keep writing - dont forget. It does really help
