So about 1 month ago my wife left the house. We had an argument over someone that she talks to all the time from work, she used to refer to him as her work husband. I was jealous that she was spending what seemed like more time talking to him then she was to me, even though I know that she never had or never would cheat on me. Well one thing led to another and she moved out and took our 3 year old son with her to stay at her mothers house. We went to a marriage counselor for 2 sessions(first 2 weeks after this happened) and I still continue to go without her. She has already said that she wants to get file for a D. I know that I'm not perfect she says that in the 13 years that we have known each other (married 7 years) she has never been happy. I see know that looking back there were times when i was less then perfect being cruel and putting her down for no reason. We have both been going to a psychiatrist for about 2 years now, me for depression, and her for coping with me and anxiety, she did move out of the house at that point so that I would see that there was something wrong with me(I refused to believe it when she told me). Its now come to the point where she will barely talk to me, gets mad if i try and do something nice for her. I don't want to lose everything that we have together, both of us have good jobs, a great home, and most of all the family.
The few conversations that we do have now, I get mixed singles from her on what she wants and its really confusing me. One day she will say something that seems she wants things to work out and then later it will be completely opposite.
For example after an argument between us that we had about 2 weeks ago now, over which began because i asked her what she wanted for us. Well looking back now that was a mistake, not only could i not get an answer from her but the argument was a screaming match. I wish i had never asked. By the end of the argument about 5 mins, she had said that she just wanted out. I left the place where this happened (my parents house). The next day, I made the mistake of going out and buying a replacement TV, what a dumb way of coping, well only to my surprise the W found out. She was so angry about it, the comment that she made to me was "Well that just goes to show how much that everything means to you." I simply replied "what does that mean? you said yesterday that we are through." The answer that i then got back is "well you never know." Talk about getting false hope. Since then I have offered to move out of the house for our son to be at the home with her, she refused, I have sent her messages in the morning to have a good day. Only for her to tell me last night to stop and not make this any harder then it is.
I have read through the entire book since all of this happened, and I must say I have learned a lot, part of me wishes i had read it years ago. I'm at a point now that I don't know if there is anything or anyway that this marriage can be saved.
