This is almost my exact feelings and situation. The only diffrence being I am younger (30) and not as experienced with life. My daughter is only 2. My W only option when she leaves is to move back to her parents, which is 300 miles away. How can we successfuly co-parent with that distance? I cry every day wondering how this will effect her (D2) and how it will effect my relationship with her (D2). The thought of not being part of her everyday life is heartbreaking. Just that thought alone makes me sob. So I believe I need to do everything possible to make my marriage work.
