Today is the greatest

[Lifes Twists]

I would tell him then that for some reason you are uncomfortable with this right now. Tell him you are not sure why and it is something you are working on. Then ask him if there is another arrangement that will work for you that I may be less uncomfortable with.

Don't try and point fingers at or directly define what is the cause. Leave it vague. He should not take offense and be willing to work with you on this.
