I agree.She was happy enough to go along with it all the time she was his girlfriend and he was spending money on her! On the other hand,when people say that they cant believe he confessed all this to her,only to go on to dump her,he possibly kidded himself that if she told on him - who would believe her? After-all,it was effectively her word against his.She never had any concrete proof did she.Only what she had learned from the relatives/police/media.
