Should I still wait for him?

My boyfriend and i have been together for a year now we met online last year and we have a really strong connection with eachother and we wanted to marry each other but we can't
His dad owns a business and he is forcing him to marry his bestfriend's daughter for some business profit
My boyfriend he's just 18 yet he'll be 19 this year
And the girl has a boyfriend too and she has been with him for 3 years but now their dads are messing all of these things
It's his wedding tomorrow
He can't even run away because the consequences of running away are bad his dad has already given him warning
But we don't want to accept this we really can't live without eachother what should I do he said we will still talk but just as friends he has already given up his hopes about changing his dad's mind he did every single thing to change his mind and so did the girl
But they both can't do anything they are getting married tomorrow
What should I do should i wait for him?
Do you think we'll ever get a second chance in our relationship i really can't be without him
Should I still wait for him?
