My Wife Walked Out

[RSG]

The more I talk to her, I see that talking about us is just going to reinforce her choice. That's not to say it's not difficult. It's hard for everyone, but harder for those of us who hate not knowing what's going on.
I've decided to keep texts related to our son, or to how she's doing at work, etc unless she asks about me.
I'm trying to work on myself. Doing reading, encouraging myself, trying to get into a couple things to get out with friends when I can, etc.

My situation: We've been together for about 5 years and married for 3+. We have a wonderful 3 year old boy who we both love to death.
I'll start with my problems. I took her for granted, in general. She'd cry about something, and I'd just tell her it's no big deal and get over it. I didn't compliment her like I should have. I didn't talk to her in a way that made her feel good. I'm quick to freak out when I'm not in control of things, and she doesn't like that at all.
As for her, she's chronically unhappy and that kind of runs downhill. She doesn't like to talk about things and will shout me down. She likes to tell me what to do.
We both have poison tongues, but she can do some real damage with hers.

I'm trying to take it slow. All that stuff above hurts, especially those things I've done wrong. I started improving after she tried to leave in January, but I didn't think she was terribly serious so I didn't look into books, strategies, etc.

I'm just trying my best to be a friend, great Dad, and to make myself better. I still run the gambit of emotions, but am better able to manage it now because I have clear goals. I'm scared to death, and I think she is too. But, I'm dead set to work on what I can and when she's ready, to work on us!!
