I have been thinking about another woman for the duration of my marriage
Is your wife not what you wanted? Is she boring?
I am just not happy with her. She tries to control me too much.
I think it is time to get a divorce then you can be free of a bland marriage and free to pursue who you like better.
I know, but I can't think of a reason to break up.
The reason to break up would be that you have a desire to be unfaithful in your marriage. This is what you have been saying, right?
