Joe - This is a wierd place to be in. You have been so successful and dedicated. It really may be that she is jealous. I don't kow her so I cannot judge but it seems like you two need to talk about it. If you don't you will begin to resent her and that will not be good for you or your relationship. You are a great man and I am sure that she knows it...she may not realize how much it really hurts you!
Don't forget that you are the BEST and also deserve the BEST!! <3
