You are not going in circles
You are making progress in a spiral. You do come back around to where you were at the start, since recovery and healing take time, but every time you come back around to that point you’re a little higher up because you’ve got more experience, more knowledge, and more strength.
You ARE making progress

You are not at fault.
Celebrate your ability to love.
