Well for one he is not being honest with him about his job, while the mc is pretty open and honest about everything. He’s giving the ml his feelings, access to his body and his home and the ml knows all of this. Yet, the ml does not reciprocate. It’s one thing to not know how someone feels about you and treat them according to how you view them but it’s becomes manipulation when you know how someone feels about you and you use those feelings to get what you want out of the situation. Manipulation is mistreatment. The ml is using the mc and the ml is grown enough to know that’s wrong.
He doesn’t run from the dick, he doesn’t try to deny that he likes the dick AND he rides the dick. Yes, you have someone very valuable and you’re mistreating him.
