Work, Love, and Buddhism in the modern setting

I am curious as to what the stance of Buddhists would be towards a couple of issues. Would it be possible to maintain a career, one that you dedicate a lot of time towards and that you actively pursue, while still devoting your life to Buddhism? Would it be possible to maintain a physical and emotional relationship with someone? On both of these issues I want to make a clear distinction between applying Buddhist principles towards life, and being a practicing Buddhist. I am concerned with the latter, treating the Buddhist teachings as your primary goal and giving it the utmost importance. In essence, I am wondering if one can gain true enlightenment while remaining an active participant in the modern workspace and relationship environment, just with different principals? As an additional tidbit, would pursuing other education or outside pleasures be possible as a monastic Buddhist? Thank you for any help!
