The guy was obviously fairly desperate to say he decided to share his story on this website, but I'll give my twopence worth.
No bloke should expect any sympathy from anyone for getting caught out like this, its not like he did it once or twice, he's been doing it for 7 years. He obviously got so used to it that he started to get lazy and didn't cover his tracks.
What guy can really say that he loves his wife if he is going to see escorts. I can fully understand the reasons for staying in a marriage that isn't 100% right. There are lots of reasons for keeping it going, kids, finances/debt, ill health, I don't believe that stigma should be one of them in this day and age.
Single guys have every right to do what they want without any feeling of guilt. I'm not sure if every single guy out there has made the conscious decision not to ever be tied down in a relationship, I suspect some of them might never get the opportunity to be in a relationship but I'm not here to judge those people, they can do what they want. I would say that any guy who says he never knew what it is like to truly love someone has missed out badly in life.
If this guys wife has found out then the only thing he can really do is say that he has an addiction, which in all probability is what he has. If his wife ever forgives him or gives him a chance to continue then he should consider himself a very lucky man. But if he even thinks about seeing an escort in the future then he may as well pack his bags.
