<human>: My wife and I have been together for four years, and married for a year and half. Our decision to marry was not for a traditional life-long commitment, and we never spoke about it as such. We have no children or pets.

About a year ago I became very sick suddenly and could no longer work, and was completely dependent on her. A lot changed in this time and the past six months I have felt myself drifting away from her. I am now back on my feet and able to live independently.

I've done a lot of thinking and reflecting, and I have decided that I don't want to be with her anymore. I still love her very much though and she is my best friend. I am scared of losing her completely, but I have started becoming depressed. I have sought professional help for the depression, and my therapist seems to agree that a healthy course of action for me would be to move on.

How do I ends things with her? She is incredibly vested in the relationship and very in-love with me. I can't continue like this, and I'm becoming more and more unhappy, but I don't want to hurt her. I don't know what to do.

Summarize the given text in a few sentences.
<bot>: I don't want to be in my relationship anymore. She is my best friend and I love her. How do I end it?
