You definitely need to get this out on the table. One thing, though, try using the word "difference" instead of "fault." So say something like "I've noticed some differences in how we work together and I feel like it's affecting my commitment to the business."

Make a list of the differences beforehand and go through them one by one with him. Make an agreement beforehand that if it gets emotional, you'll take a break on the current item and revisit it after you've each had a chance to process it.

Also, ask yourself if there's anything you can do to change how you perceive those faults.

For example, I used to get defensive about my code when my partner criticized it in a certain way. One day I realized that, if I just wait 5 seconds before responding and remind myself that my partner has the best intentions in mind, the emotion drains away.
