Stressed About the Direction My Life is Heading

What do I want to do with my life? I'm getting so caught up in this dilemma right now. I see two lifestyles ahead of me. I can stay in one relationship, in our house, running my business, maybe getting married, maybe having kids. I can try a new relationship, I can leave everything behind and go after a crazy big dream of being a traveling musician, seeking adventure. Could I find a compromise between both? Do I want that? Would I be half-assing both? Would I be lukewarm for two things instead of a raging fire for one thing?

I feel I'm approaching a fork in the road and I'm scared and I don't know what to do. I have dreams and I'm doubting whether it's the actual dream I want or just the feeling I'd get from that dream. Maybe I can get that feeling from many different paths?
