Get yourself and your wife a gym membership and a personal trainer, your extra money will be gone, you'll both look and feel better and fuck more.
The urge to see escorts will be less, you can still go once in a while, but it should definitely help with the addiction and the urge to find someone on the side.
I made the gym example because that's what's worked for me, but any hobby or physical activity you can do 2-3 times a week with your wife will do.
Another good idea I can vouch for is spending your extra money on something else other than sex that you can both benefit from, new cars, cottage, vacations, designer bags for the wife.
Most people on this website have either found a way to balance the real life / hobby ratio right or have found out the hard way how expensive a mistake of this type can be.
You're one step away from a very slippery slope, step back while you can.
