Loves him so much

So me and him have been friends for 3 years and been together for well now 9 months and he can't have children and I can but I'd so like to wait but also I've been going baby crazy I know I'm suppose to wait patiently but should I force him to get rid of bad habits like not taking vitamins and smoking so much so me and him can finally have a kid or just wait til we are both financially stable and then get things started because it feels like if I don't whip him into shape about those regiments the count down there will go low and we might not ever have kids like I want in the future I know I need a period for each sentence sorry
