Didn't really answer the question, though. From other posts of yours I'd gotten the idea that while you were in the UK this master had told you he would be monogamous, and that before you even joined him in Australia it was clear that this was not true. If he told you he'd be monogamous and now he's not, then you have deeper problems than the online slave. If you just assumed that he'd be monogamous out of respect for your past, but didn't discuss it, well, then this is a perfect time to do that.
