I think you should draw the line here and not put up a picture of JR. Sounds like she doesn't draw many lines for you and has been very, very open to change for you. I personally think having a girl around thats a little jealous is a great sign.
Can I assume perhaps there is a little more involved, like you've actually met her each of those times for an autograph?
This is one of those "will he do what I ask?" issues for a woman. If you put up the pic you might as well kiss your marriage and the pic goodbye. Not in that order ofcourse.
You can do what a woman asks and still maintain your macho.
Does this ring a bell? "Do you promise to love, cherish, and OBEY . . . " ?????
