Mirage, a real Dom is a leader. Part of being a leader is born, part is made. The question is whether you are willing to wait and to put up with the multiple uncertainties that are part and parcel of him learning to lead, or whether you are not.
Only you can answer that question, and coupled with the various portions of advice above (some of it excellent, as was pointed out), I wish you the best in coming to a brutally honest answer for yourself.
