I want another baby but husband doesn’t

nurture family, I need your advice. I desperately want another baby but my husband is adamantly against the idea. So bad that it’s hard to talk to him about it. A little background, we are 8 years apart, I’m 36 he will be 44 next month and has a 15 y/o from his first marriage who we have full custody of. So in his mind “we” have 2 kids, which is technically correct. HOWEVER, I want 2 that I’ve felt grow inside of me. I loved being pregnant, everything about it and being a mom to my daughter is the best thing I’ve ever done! I want her to have a sibling close in age. I should note that my delivery was a little crazy because I developed HELLP syndrome at 35 weeks and had to deliver early bc my liver and kidneys were literally shutting down. Another reason why he doesn’t want to risk it. Which I get. I’m worried that for the rest of my life I will be longing for that second baby and end up holding a grudge against him. Time isn’t really on our side at this point. We are clearly at a crossroads.
