I would guess that she is cheating. He can't really win this. If he tells her he doesn't want her going out without him then she will call him controlling and leave him. He could try playing the same game and go out on his own and not explain where he's going. If she doesn't care then she is definitely cheating.

Psychology 101. People are always influenced by what they themseves think and do.
