Perhaps there was something there between them when they lived together. Maybe just friendship, a brother/sister sort of thing.
Maybe they both had deeper feelings for eachother, and remained friends.
What makes me suspicious is that she is very poorly covering up something, that if it were totally innocent, should have taken all of 30 seconds.
I think you should go to his place, and ask him directly to come over for dinner on Friday, and when he does, just tell him you are confused about the amount of time he spends in your home when you are not there. He would hopefully connect the dot that you likely don't like her going to his place either.
Just be straight about it. I'd just ask him, while she is sitting there, if you have anything to worry about, or do either of them have anything to say that you should know?
I would say that if that doesn't put the kybosh on whatever is going on, then you need to have some serious talking with her, preferably with a counsellor involved.
