A coaching relationship is temporary, It can be three, 12 or 30 sessions, might be two months or two years depending on your goal, but it has to end.
Although you usually sign up for a defined umber of sessions, it could be easy to become dependent on your coach and some less than scrupulous coaches could take advantage of this to ensure revenue from you as long as they can. A serious coach must avoid you build a dependency.
The coaching relationship has to evolve in a way that there is a natural end to it, however strong the relationship may be.
So, at some point it means that as a coachee, you need to begin a serious work of assimilating what you get from the coaching. My advice would actually be to do this regularly during the coaching and your coach should ensure it happens.
Take stock of what is and how you are different from at the beginning of the coaching. The aim of coaching is for you to learn, grow, develop and become more aware.
Reflect on how all these have happened. If you feel no progress is made and it is a fair assessment, the coaching relationship needs to be questioned. What is not working? What would make it better? Is it better to end the relationship?
Coaching is to make you a better person, the person you want to be. Make sure it is the case.
