Well, I didn't feel comfortable using my first name - it felt too exposed at the time. I chose Heart2Heart because that's how I saw & see us - connected at the heart, despite the current sitch. Perhaps I'm just a silly romantic.
I also didn't like some of the sad names - well, they made me sad and I didn't feel like that.
I sorta see this discussion on how we chose our names, as part of a broader discussion of what we feel inside and how we project that to the outside world.
