Is she the one initiating the hook ups? Is she seeing someone else? If so, I'd stop that to avoid getting an STD personally. If not (and if you're really sure about that), maybe try just to have fun with it and not read anything into it. I hooked up with my WAH once and it filled me with hope. Guess what? He took off his ring two days later and left town? Then, later, we hooked up again (both his doing), and guess what? I didn't feel a thing for him. Had to fake it for the first time in 15 years. It was disappointing but also empowering. I'll not be missing that anytime soon, and he will have to have an STD test before I welcome him back (if that even happens). So if you still enjoy it and avoid letting it lead to emotional attachment and expectations on your part, then go ahead. If not, maybe make that one of your boundaries.
