Need to vent and need some words

Starting to think I'm wasting my life away with partner. We love each other but it's not enough anymore honestly. We fight all the time , months without sex or any intimacy. When I try to talk he shuts me down and doesnt want to try to repair anything. We lost our son in 2020 and wanted to try for another baby, I have so many medical issues that are making it hard to even get pregnant let alone keep the child and it's been rough. I'm also 27 years old and fear for my future. I want to be married and have a family one day, thought it wouldve happened by now. He has no desire to marry me or even take a step and get engaged and these words came from his mouth, but he wants a baby? I've already been on the fence about trying to kids since he doesnt want to get married, but I gave in last night because I was ovulating and we didnt even have sex . All he cares about is sitting on his phone and having all his friends come over to buy weed . Its draining and at this point I dont see a future at all just ready to move on and do things I want to do with someone I'm compatible with. I guess I'm asking if it's worth trying and fighting still or just leave
