Can you afford to live on your own? Is she the reason money got tight? Sounds like she has a new love, (money)? Hard to kick that monster out. Might be best to go separate ways. If, and I mean a big if, you tell her how you feel and she quits escorting, how will she then feel towards you? Most likely she will dump you and find a way to becoming an escort again. Might as well face the music and to quote Barney Fife, "nip it in the bud".
