I used to be so lonesome for my H too as all of us here have. It just takes time, their time.
As far as really letting go, it took me a very long time to get to that point. I learned alot on the way. I knew the more I pressured my h the farther away he went. I gave it to God and finally found peace.
My H lived with the ow for a couple of years. When he finally did come home is when I found out it wasn't all a bed of roses over there once the newness wore off. Hang in there.
