“Lilmod, I have asked others (to be specific goyim) and they said that they think I should tell him but I personally do not feel comfortable. So that is why I was asking other people (to be specific Jews).”
Rebshidduch, I am very reluctant to give you any more advice since you just seem to get offended when I do.
In any event, I think you are capable of figuring out the answer yourself.
You wrote that you do not feel comfortable telling him, and you want to ask other people (specific Jews) what they think. You are Jewish; how about asking yourself what you think?
