Ruby, the only way to know why that person walked out on you is to ask them why they walked out. It's tough to know the answer if that person refuses to speak to you.

Honestly, I've walked out on all my friends. I even had a friend for 12 years that I just let go. Why? Because none of those friends were healthy to be around. All they did was talk about their ridiculous problems. But they never talked about solutions. Most of the time I was pulled into their chaos.

I've also let go of friends that I liked for a few years. But then things went sour quickly when they expected certain things from me. I only live for me, not for them.

Also, many of us grow apart over time. To this day, I question if there is such thing as a true "friend."
