Our dreams are so different

I’ve been with my sweetheart for 9 years now, since we were 17 and I love this man with my whole heart. Our families have become so big and so full and there has been nothing but love our entire relationship. (Not that there hasn’t been a shit load of work)

But as we’ve grown up together and entered early adulthood and grown out of it, I’ve realized that we have two entirely different dreams in life. I want nothing more in this world than to be a wonderful wife and mother, and am working hard in a design career to be able to someday afford that. He wants to be this business man type, mansion, servants and workers all at the house with constant updates on work. Assistants and crazy looking cars and an extravagant lifestyle. He reads more self help books than he does listen to anyone in real life’s advice.

I don’t want any of that. I like my solitude, I like living in a home that fits what I need (no more no less), I don’t want to be rich I just want to live my life happily. I just find it hard sometimes when it feels like we want two entirely different lives. It’s gotten to a point where I don’t get sad thinking about it anymore I just want us to both do what we’re doing and if we don’t end up doing it together it’s okay to me. He says he wants to marry me, but I don’t want to live the way he wants to and I’d hate to force him to go against his dreams. Is this a bad sign?
