I want to tell my wife I wanted to travel to europe without her
Why would you want to travel around Europe without your wife?
I love travelling by myself. I find it is more fun to travel alone.
You can tell her this but be prepared for her to be upset about it. Married couples are expected to travel together on vacation and she would be hurt to hear different.
She does not like to do the things that I do when I travel.
Instead of telling her you want to go without her, try and make a schedule to appease both of your needs. I doubt she would be happy at you going alone, so this is the best option.
