I agree with Anita that this is just your ego causing the strong emotions to rise. You’ve lost your safety net.

People should not be treated as safety nets.

Your culture probably wouldn’t approve of the union. If you didn’t feel it in you to welcome him in your life officially for seven years, it’s not worth it now as the conflict and drama with family would be very hard on you both. I wish you luck with a future partnership/arrangement that works for all parties. The only thing I would suggest is writing him an apology for stringing him along for seven years. That would probably go a long way to ensuring that things don’t end on an entirely bad note.
