Sorry you are here. I'm sorry any of us are here. The things you are dealing with sound so similar to what I have dealt/am dealing with.
My wife has been pregnant by 2 different OM. Neither carried to term. One by abortion, one by miscarriage. In both cases I was prepared to raise the child as my own. You see, it's not the child's fault. They still deserve to be loved.
And like you, my wife only sees me as her friend. A couple weeks ago she told me that she didn't love me in a romantic way, but just as a friend. I will take that for now because a few short months ago she hated me, so it's a move in the right direction. She said her love for me gradually disappeared, but she told S12 around the same time that she was just pretending for the 13 years we've been married.
For all the things they say, their actions betray them. My wife was so concerned because I got my fleece dirty that she went and got me a new one. And just this morning she texted me to make sure I got to work OK (we've had some bad weather). If I were to bring it to her attention she would just say that she was being a good friend even though she doesn't do this type of stuff for anyone else.
Continue to be his friend. You're building a foundation for later. If you reconcile, you want your relationship to be based on a good friendship.
