Is it too demanding that I want my bf to tell me who he is going out with
It might be seen as controlling. Is there a reason that you want to know?
I want him to be honest
It is wrong to try and be controlling in your relationship. It would be better for your relationship if you can trust that he isn't being unfaithful when he goes out.
So, I'm just supposed to trust him.
Trust is one of the most important things in a relationship. You should feel you can trust him unless he's proven otherwise. You don't want to be constantly worried about what he's doing when you're not around do you?
