This is one of those positions where you need to sit on your impulse to keep reaching out to him. He felt suffocated and hence he needs space. If you pursue him you are likely to compound the problem. This might be the ideal time to really invest in self control. If you allow your emotions to lead you, to override rationality, then you will be perpetuate the problem that has led to this situation in the first place. Be patient, keep busy, have faith. Don't chase, don't beg. Let him have time to honestly reflect on what he wants.
