I don't let my kids tell me what they should do, I tell them what weight they will fight and when they are ready to fight. If you are his trainer, you need to break him down and let him know what you say is the law. The only voice my kids hear is mine, they can be in an auditorium full of people screaming and all they hear is my voice. If he's a 130lber, then that's where he should be fighting, no if's and's or butt's.
I am helping him out more then anything its his life,i pointed him towards a good gym but the kid is stubborn his trainers tell him the same thing i tell him,i just think he lacks the dedication to make weight.
