How did you plan your life with your husband? Need advice please 😥

My partner and I have been talking about how we are going to get married, buy a house and have kids. When it really comes down to it, we want the same things, but at different times. 
He wants to buy a house, get married, then have kids when he has a more stable job. I've always wanted to get married young, buy a house, then have kids.. but it seems a long long way away. He doesn't think I'll be successful in my career choice, so he wants to get a better job, I've told him how much it hurts when he doesn't 'believe in me', I have dreams and goals I want to achieve in life, but he doesn't see them as achievable :/ He wants to get a better job or study, so that means I'd have to put my dreams aside so he can study. If he chooses to study, we will have to wait even longer to get married, buy a house and have kids. We will be 30 something by then.. why does this feel so hard 😢 How did you ladies make everything work? Did you have a plan?Â
