Why is the feeling not going away?

I should be angry, resentful, eager to move on, with a desire not to ever look back. But those random images and far gone moments creep in. Why though? Why do I feel like I have lost something? feel like I regret? feel like I want things to go back the way they were?

You were comfortable in a way...The life I left behind was somewhat predictable, and even if it was not ideal, I had someone.

The unknown is scary.
