My DH travels a lot for work, mainly Europe and Russia. Recently he has made several trips to the Ukraine. I thought nothing of it but on one trip he said that he was in Paris but I found luggage's tags in the bin that were for those dates and from Kiev. I was a bit suspicious. One of his work notebooks was lying around and so I had a little flick through. There was a woman's name with 'not exclusive' and 'STD' underneath. Also '£10k'. He has his own bank account so I cannot look at his spending. He has never given me any reason to think he has cheated on the past. In other bits in the book there are some references to sex with hotel names and reminders to pick up viagra. In another bit there are dates and what could be amounts of money, hundreds. I am obviously devastated. We have children and have been together for years. Would you think from this that he is using a prostitute or could it be a work colleague. It is those words under her name that make me think it is a prostitute, and the sums of money. I am in shock and not sure what to do. Apart from being so upset at the betrayal we are not by any means wealthy enough for this kind of spending!!!! What should I do?
