September last year is when she says she's not sure it's going to work out. About a month later she tells me that she had kissed a guy during the summer, but that she's not seeing him any more. A month after that I found out from her sister that she is still seeing the same guy, I confront her and she says they are just friends, but she'll stop seeing him.
She still ends up moving out on new year's eve. Two weeks later I finally decided to look at the phone line and end up finding out that she's been talking to OM a lot. I know who it is and I confront him about it. He says that while they have talked a lot he doesn't feel about her that way and would stop talking to her. She was not happy about that conversation I had with him and told me it was over the next day (1/14).
Since that time I've learned a lot about what I've done wrong in my marriage - mainly leadership and setting boundaries for her and the family. Not that I take all the blame as she had issues with being overly critical and can be selfish at times.
I also learned a lot about how poorly I acted from the point she told me she wanted to move on until the point she told me it was over. I was way too emotional with her and never showed myself to be strong or confident during that time. I have tried turning those things around and she has noticed, but has told me it's too little too late.
We are currently working on the divorce papers (not wanting to go to court or a mediator) and I would assume they are going to be done in two weeks.
