Where do I go from here?!??🤷🏽‍♀️

I’ll try to make this as short as possible because it’s kind of a long story; so my ex and I were in a 10yr relationship. We reached a point in the relationship that we couldn’t compromise on moving together,marriage and kids. I feel like because I love him so deeply, I could never have kids with anybody else. I feel like I can marry someone else then again I might not but I know I could never carry another man’s child( how I feel right now). My ex and I always talked about getting married and having a family. I trusted him beyond belief. I still do because we are still great friends but I have to learn to shut down my relationship feelings and only allow my friend feelings to care for him from a distance. So what happens if I find someone that I wanna marry or that wants to marry me and I still have the same feelings about not having a child? I am open to adoption but would that be enough?
