Pal reckons another man has been on my new woman?

Im a 61yr old male. i left my wife 5 months ago, i figured i have only a few years left and i wanted to live them happily. My wifes 56 and basically hadnt got my drive. I was lucky enough to have retired on a very healthy sum of money and have property all over the city. I moved myself into a penthouse and got a stunning russian 24yr old to do my cleaning. To cut a long story short, she made it obvious she fancied me. We are now an item and the lady is a stunner. Shes able to match my drive and she has enormous 32G bosoms. They are natural, not plastic. However, i'm feeling real jealous as she tends to flaunt herself with younger men and my mate saw her down in a bar with another mans hand on her backside. He said he wuold be pretty certain the other man could be having a go on her...what shoudl i do?
