Making him happy🤔

So Iam 37yrs old have two daughters 21 & 19 met the man of my dreams married the man of my dreams buttttt the man of my dreams doesn't have any kids!! He asked me if I wanted more kids when we 1st got together and I said nahhh I don't wanna start over🤦🏽‍♀️ and he was ok with that!! Than time went on the girls went to college and now he makes lil statements about being a dad! Butttt he says he will still love me if we don't have a baby! It's crazy cuz he looks soooo happy with his god kids and his nephews!! And now I feel like I wanna give him that happiness😔 am I being selfish to myself😩 HELLLPPPPPP🤦🏽‍♀️
