It's a difficult choice in some ways as you, and your boyfriend, obviously want a job. I would be very dubious of the actual job but the chance of an interview is difficult to turn down, and I have experienced the dilemma.
It doesn't seem to be that good to be true to me, given the details above, and if it is the same company.
If you feel you should turn it down, and that's your choice, remember he has your personal details from your CV. So I would be polite, not mention scams and infer you have another job or something. As hard as that may be.
Or go, and be very detailed about what he actually expects you to do, the hours, how you will be paid ie salary or commission or combination, the details of the employment contract etc etc

good wishes
