Maybe she just want to connect with you on a deeper level? It's weird of her to feel this way when you don't currently have a girlfriend! And SHE has other men!
I like what Autumnal said -- then she is willing to break up with her men, right? How is she going to respond to that??
Or is she possibly getting serious with one of them and looking for a way out of the marriage, so she can go be monogamous with someone else? Passively seeking a way out, but wants it to be YOUR call?
