All I can tell you is I know exactly what you are going through. I SO badly feel like calling my W, just to hear her voice. None of this makes sense. She's hurting, I'm hurting, my kids are hurting, and for what? Because she thinks she's in love with a guy she met a few short months ago. For that, she bailed on an 18 year M and left me with our 4 young kids. I miss her so badly sometimes I feel like I can't even breath.
I don't think there is any easy or quick way through the pain. You just keep moving ahead and let time heal the wounds. What I tell myself sometimes, just to help me feel a little better, is that if I get to a point where I've totally given up on the M, then I will reach out to my W and develop a solid friendship. It's what she wants now, and I'm sure she would be open to it. At least then, we could talk, and maybe even hang out once in a while. Of course, by the time I reach that point, I may not want a friendship with her, but it helps me to think it's a possibility. The thought right now of going through the rest of my life this way, barely seeing or speaking to her, is unbearable.
