What you need to remember is that 30 days no contact is an average duration to recover from a breakup, assuming you have followed it correctly in the first place. Your question implies that you are not emotionally strong enough to re-engage with your ex. You clearly recognize the trauma that his rejection will cause you and this indicates that you are still in a vulnerable state of mind.
I would not recommend you initiate contact with him just yet. Let it run for another few weeks and reassess how you feel then. If he contacts you in the interim, and you feel strong enough to see him, then that has to be your decision. However, please consider how you will feel if he gives you the, 'let's stay friends' spiel, or alternatively, breaks the news that he is seeing someone else. While couples do reunite, don't pin all of your hopes on this happening.
