I hope she's "dating" others also. if not why the heck not?
I've not closed it off to her. I told her from day one I am not about to have any exclusive relationships until I let her know otherwise.
We already went over it last summer when I dumped her til after Christmas because she was getting all stalky, and coming over, and calling when I had other dates. So she knows where I stand. And when she was pulling her "I'm always faithful to you" bullcrap, I was letting her know "I never asked you to, don't lay your volunteer work on me."
Not my problem, though. I didn't take her to raise, and I have no responsibility for her quirks, neuroses, or self-denial.
