With the way you banged me all night long so shall they bang your children and not pay them

This is a whatsapp conversation between a boy and a girl, it all started when the boy bolaji invited the girl for a hookup, and they agreed that he will pay her the sum of 15k after having sex with her.

So after the whole thing its time for the guy to pay her the amount they bargained on, the guy transfered fake alert to her.

So when she gets to know it was already late, then she chatted the guy up on Whatsapp telling him to pay her, her money, she even said the guy borrowed 2k from her promising her that he will transfer everything together

So the guy got angry saying, she ate fish 2 plates, he bought 2 packet of condom, she drank 2 bottles origin 1k, And they both enjoyed themselves

See screenshots below

So who is at fault? Who is to be blamed? Is the guy right for what he did?
