I dont know if i want to be with him anymore

Back story, my and my so met last year on an online game and we had instant chemistry and we soon got together and met up in person (200 miles apart, and im 23 and he is now 21). I trust him and i trusted him then which meant i was comfortable telling him very personal details. I have pcos, i dont ovulate and i have all sorts of other problems and at one point i told him this because we spoke about having children one day (sounds very early to speak off and i did tell him i May struggle, or may not be able to have them at all. And he knew this from the start). Well we have now been together for a little over a year and my health and worries about my fertility have gotten worse and so i had a chat with him about it all and lets just say it left a sour taste in my mouth..... he said he loves me and wants to be with me forever, but if in the future I can’t birth him a child..... ahhh he doesn’t know if he will stay in a relationship with me. That left me feeling angry, heartbroken and like a freak. The fact i may lose the love of my life because of something that isn’t my fault, something he knew about from the beginning.... i just 😞. I understand his want to have children, it was the same before we even got together. I feel like he has wasted my time and i dont feel good enough for him, I don’t feel the exact same towards him anymore...... I already feel depressed about the fact i may not be able to have children but this? It makes me feel like im not a woman and that I’ll never be good enough for anyone 😢😢

I really want to express to him how i feel, but he is going through a hard time atm because his parents are divorcing and i dont want to make him feel worse......
