What do you think about me exploiting my boyfriend's trust?
Do you mean that you take advantage of him when he trusts you?
Yes, it irritates him mentally, and I make him feel like I am very dangerous.
It's wrong to exploit someone for your own purposes.  The more you keep up with this kind of behavior, the more likely it is that your boyfriend will leave you, or start to take advantage of you in return.
It's fine. He's okay with it.
You should not assume that your boyfriend is fine with you exploiting him in anyway. This is wrong to do and in time your boyfriend will get tired of it and tired of being mistreated.
