What do you think ?

I'm 19 my boyfriend's 20. We've been together for 3 years . I have my own place and work to pay my own bills .. My boyfriend also has a job but lives with his grandma .. He'd rather spend money on new shoes and the latest fashions .. I really think I'm ready for a baby but he doesn't think so .. And says things like "it'll happen when I'm ready or it'll happen when i put one in you" I feel like he should grow up and be a man .. Am I wrong for feeling this way ? 😫
