Just Friends?

Hi,
Discuss it in the old Christian way: Honest and true.  Choose the setting, prepare what and how you want to say, start by saying that your friendship is of utmost importance to you and you don't want to do any harm to it..... but.... then say exactly how you feel and what you want.... say that you'll accept and respect any reply and you'll appreciate a true honest answer (just as you put your question).   After doing it you'll realize that it was much more simple than you thought.... 
Good luck,

Best way to find out if he's feeling the same way is to ask him. Just note that living with someone, and working with that same someone may eventually get on your nerves.

i agree totally with what the others say, but if you find it hard to be blunt and simply say "do you want to date?" then you could possible do it the simple old fasioned way and be provocative? men are (though i hate to admit it..) as simple as a light switch, as you live together there are many simple ways to be provocative, and that does not mean you have to be rude. but if you show him the right signs at the right times you will know in a second how you stand with him, once you know that asking the question will be as easy as pie.

I agree with Oron and the others.  Just tell him how you feel and then if he does not feel the same way, just reassure him that you respect his feelings and decision and hope that this won't affect their friendship.

Honesty here is very important.

Tell him how you feel. Living together and working together may cause problems and make it difficult to sustain an emotional relationship. Simply put "nothing ventured, nothing gained".
