Long post..I'm not sure how to feel...

So backstory real quick. Hubby had a vasectomy with his first wife after 4 kids. He finally got on board to do the reversal, as long as I had testing done first (completely fair ask, I've had several miscarriages prior to our relationship)... well he is military and deployed overseas. He was supposed to be coming home and while I know exactly what goes along with the uncertainty of deployment the pandemic has changed things. We dont know when he will come home now. I just don't know if I want to continue on this journey of TTC. After years of me wanting him to WANT to have a baby with me, he is finally on board, and it's one thing after another to prevent it. I'm afraid I've lost hope. When do you decide it's not meant to be?
