B - I am really sorry and I can relate to what you are feeling. I came to terms with my EW leaving but it will take me a very long time to come to terms to what she did to our girls. Accepting that has been the hardest part for me. I will move on, find love again but my girls will only have pictures to remember their mommy and daddy together.
With that said I do believe god has a plan for us and while I may not know what it is I do have faith that he has thrown me this curveball for a reason. I just know that I will not waste this opportunity. I will continue to work on myself, try to be the best father and partner I can be, I feel that I have a better grasp on R's than I ever did before, and I hope to take my experiences and growth to my next R and it will blow what my EW and I had out of the water.
Keep moving forward B, try not to look in the rearview mirror. Most people on the board equate success with the S returning to the MR. For the longest time that is all I ever wanted. I DB'd my ass off however in the end she didn't return, she never moved closer. Does that mean I am a failure? Just remember that the S returning to the MR is not the ultimate sign of success, I know it's hard to see but it's the truth.
