I am not even sure if I am capable of fulling letting go, but it is time. It is now about ME.
Trust me, you are. It will take some time and effort, but, you'll get there. I didn't think I'd ever be where I am (finalizing D paperwork before filing) because I thought I loved her too much and couldn't live without her.
Not saying at all this is where you are headed. However, you will eventually be able to work thru whatever emotional barriers you have and get to a point where you make decisions based on what is best for you, your D and the future, and not necessarily what you want today.
