This is interesting because I've just dealt with the same problem (balancing a relationship and music production AS well as looking for a professional job) and it's almost comforting to see that it's a common characteristic for those dedicated to their music to spend every minute they can on it.
It also shows, though, that there needs to be balance. Everything about life is about keeping it near equilibrium, moving forward but still balanced (not complete equilibrium because then that means death

), and in order to have a healthy music life, love life, and any other life, there needs to be a balance. I've tried doing this by scheduling. For X amount of hours I spend time dedicated to networking, another x hours is for production (I try to keep it like a job during the week, and a hobby on the weekends, so it plays both roles, lol), and family&friends need us/we need them too, so for a weekend I spend x amount of hours hanging out with them and during the week I make it a point to cook for my parents & sisters and have family dinners. Then the obvious x for a relationship.
Though I will be honest, I decided that I would rather spend more time on my music production, so it is also about compromise, and I decided that my love affair with music was more important to me than the relationship I had at the time. If you all think girls are needy, don't fool yourself in to thinking men can't be needy, too
