Feel like I've lost everything 😪💔

I recently had a miscarraige at 6 weeks , me and my partner were going to try again in 3 months but today he told me he doesn't want a baby as he can't go through the heartbreak of losing another baby , I tried talking to him expressing it was our first miscarraige and it does not mean it will happen again but he's not listening and it's something I feel differently about I readjust want to try again soon and have his baby ... I don't know what to say or do I feel like his decision is breaking us apart ...Advice please
