Basic principle of US immigration law is that you can only hold one status at a time. Also O-3 status does not allow work, which includes looking for work. To look for work, technically you have to look for it outside of the US, and then enter in B-1 (visitor for business) to attend a job interview that was set up specifically for you.
Having said all that if you got a job offer and the letter for TN you could just leave, go to the POE and apply for TN-1. Your visa would still be stamped in your passport so that will raise questions from USCIS because to enter on TN-1 you must have "bona fide non-immigrant intent" because it's designed for temporary employment. Telling them you're entering to live with your boyfriend who is on O-1 might get dicey if you get an FTO who is a stickler for the rules because you have an intent to reside in the US as your principal residence.
My advice (which isn't much help I'm afraid) is for you to get married, and for your then husband to get his employer to sponsor him for permanent residency. Then you get it too.
If he's in O-1 he should qualify for EB-2, that is reasonably quick to process.
