WAW/MLC help

[Dave981]

I don't want to make this long but looking for support. W dropped bomb that she needed a break and wanted to move out to have some space. She gave all the reasons listed in DR book. Wall around her heart, feels numb, not happy etc. 8/4 she rented a house 2 miles away and will move out in September. I am devastated beyond belief. Throwing up every morning, lost 10 pounds in 2 weeks, crying every night. I bought DR and have read in 3 times in 2 weeks and have begun implementing some of the things I have learned such as "more of the same" cheesless tunnels, 180 which gives me hope. No affairs, no physical abuse by the way. The hard part is that if you saw us you would not see anything wrong. She kisses me every morning and night, waits at the door and waives as I go to work,has coffee with me in the morning, texts me,and asked me to go to lunch etc. She even looks at me with love in her eyes. We sit down and talk every day, no arguing (just some grumpiness when kids are acting up) In fact she just called as I was typing this. Basically many of the small things you are looking for when things are improving I already have as she is leaving!
I think one of the most difficult things, besides how I have offended her in the past is that our 2 year old is so challenging, and when she starts screaming the W takes it out on me. Numerous times over the past 5 months she has mentioned that she is depressed, wants to run away or be alone without anyone around when our D acts out. While I work on myself my hope is this house she is renting is an escape pad where she can go alone for quiet time and to think, and as she says maybe miss me again. Just looking for support and advice as I wade through this difficult time and slightly unusual situation after reading many other posts.
