Yes, it is true that you have to completely let go for a multitude of reasons.
1. It allows you to place the focus on yourself, which means you are using your time wisely. If/when your H comes out the other side, you will be that far ahead and better prepared to support him. Or will you be better prepared for a new relationship in the future.
2. Having '0' expectations, removes you from the emotional roller coaster. You can stand outside the roller coaster as an observer or walk around the amusement park taking in more pleasant sights and smells. That's why detachment is so important.
3. It allows your H to move through the process without you interrupting it.
4. All the above, will relieve some of the anxiety.
