Usually when there is a back and forth like this as you describe, it doesn't look good for a lasting relationship. If there are worries now, it is har dfor that person to just turn around and feel that everything feels fine and they want to proceed with a full relationship. Whatever he is feeling is causing him to want this break. I would give it to him and see how it plays out, but my hunch says this doesn't end up as you desire.
Let me know how else I can support you.
