Traveling with my boyfriend and staying for one night will not be an accident.

Maybe. Maybe he's an organ dealer. He peeled off your stomach, took an organ, sewed it up, and left you to fend for yourself. Maybe he tricked you into a strange place, then raped you and sold you today. Maybe his friend got you drunk and gang-raped. So, go home, be a good girl, and don't let your parents worry!
