Tbh very honest, paying money will not solve your problem. This will be a loop. Ignore the situation. Because, first, paying money for sex is not a criminal offence per se. Secondly, he would threaten you but will not pursue it legally because his connection with the girls will be out and it is not in his interest. Thirdly, cases like this doesn’t hold up in court.
Dont ever pay money, The greed will never end.
