Well the reason why i believe that shes not telling you about her feeling is because either she may have already done it to a previous crush and was let down hard or that hes may be a little hesitant about what your reaction would be if she did. Another would be the relationship experience, those who have had a bf or gf for a short amount of time are prone to think that it may be impossible to be in one or that the emotional side of one can be a little difficult what with trust. If you would like to i'm just putting this out there, have all three of us talk about everything and see if i cant help you two get comfortable and perhaps get on the path of you two becoming a sweet and wonderful couple. Just IM me if you have any other questions that id be glad to help you with.
